✅ Correct Answer: B) with

📚 Explanation: The phrasal verb 'deals with' means to handle, manage, or take action regarding something. In this sentence, it suggests that the person handles or manages the distribution of cosmetic goods.

While 'deals in' is specifically used for trading or business, 'deals with' is often used to describe managing tasks or items. This preposition correctly links the subject to the items being handled.

✅ Correct Answer: A) When Christmas celebrations occur everyone is happy.

📚 Explanation: A complex sentence must contain one independent clause and at least one dependent clause. The word 'When' introduces a subordinate clause that provides the timing for the main action.

This structure transforms a simple statement of fact into a multi-part sentence with a logical time connection. The sentence remains grammatically complete while adding a layer of descriptive detail.

✅ Correct Answer: B) five-hundred rupee

📚 Explanation: In English, when a number and a noun act together as an adjective to describe another noun, they are joined by a hyphen and the first noun stays singular. The word 'rupee' describes the type of note, so it does not take an 's'.

This specific rule prevents the phrase from becoming plural before it reaches the final object. It is the standard way to describe denominations, such as a ten-mile walk or a two-hour delay.

✅ Correct Answer: B) it is snowing

📚 Explanation: The present continuous tense 'is snowing' is used to describe an action that is happening right now at the moment of speaking. Since the time is specified as "nine o'clock in the morning," it refers to the current weather state.

This form provides a vivid description of an ongoing event in a specific location. Other tenses like the simple past or simple present would not capture the immediate nature of the scene.

✅ Correct Answer: D) calm down by oneself

📚 Explanation: The idiom 'pull yourself together' is used to tell someone to regain their self-control or to become organized after an emotional upset. it means to stop being angry or sad and act normally again.

This expression emphasizes the internal effort to reach a state of mental peace. It is a very common phrase used in situations where a person needs to find their composure quickly.

✅ Correct Answer: D) am afraid

📚 Explanation: The expression 'am afraid' is used in English to politely introduce bad news or to state a negative possibility. It shows that the speaker is worried about a specific outcome, such as the patient's condition.

This phrase does not always mean physical fear; instead, it acts as a way to express concern or regret about a situation. It is the most appropriate choice for discussing a serious medical prediction.

✅ Correct Answer: B) took

📚 Explanation: The word 'took' is the simple past form of the verb 'take'. Since the sentence mentions a specific time in the past, "last night," the simple past tense is mandatory to describe the completed action.

Using the present perfect or past perfect would be incorrect because those tenses are generally not used with specific past time markers. This choice ensures the sentence follows the rules of historical timing.

✅ Correct Answer: B) look down

📚 Explanation: The phrasal verb 'look down upon' means to regard someone as inferior or to treat them with contempt. In this context, the sentence is an instruction to treat marginalized people with respect instead of looking down on them.

It describes a social attitude of superiority that the speaker is arguing against. This combination of words is a powerful way to talk about social inequality and human dignity.

✅ Correct Answer: A) Racial killing

📚 Explanation: 'Genocide' is a term that refers to the deliberate and systematic killing of a large group of people, especially those of a specific ethnic group or nation. The word was created to describe the most extreme forms of human rights violations.

It focuses on the intent to destroy a whole group of people based on their identity. This makes it distinct from general murder or accidental slaughter during a war.

✅ Correct Answer: A) by

📚 Explanation: When asking for the time shown on a specific watch or clock, the preposition 'by' is the standard choice in English. It indicates that the time is being measured according to that specific instrument.

Using 'in' or 'on' would be incorrect because 'by' suggests a standard of measurement. This is a fixed prepositional usage that is essential for asking about time accurately.

✅ Correct Answer: A) would

📚 Explanation: When the main clause is in the past tense ("I was sure"), the following clause must also use a past form to maintain consistency. 'Would' is the past form of the future auxiliary 'will'.

This structure shows a future event from a past perspective. It helps the reader understand that at that specific moment in the past, the meeting was expected to happen.

✅ Correct Answer: A) Ardent

📚 Explanation: The word 'impassioned' is used to describe someone who shows great emotion or intense feeling about a subject. 'Ardent' is its closest synonym, meaning very enthusiastic or passionate.

Both words describe a state of mind where a person is deeply committed and emotionally invested in what they are doing. This is the opposite of being unemotional or neutral.

✅ Correct Answer: A) Culminating

📚 Explanation: 'Climactic' refers to a moment that is very exciting or important because it is the final point or the peak of a series of events. 'Culminating' shares this meaning, referring to reaching the highest point of development.

This term is often used to describe the ending of a story or a major historical event. It should not be confused with 'climatic', which relates specifically to the weather.

✅ Correct Answer: A) He told that grass is green.

📚 Explanation: When reporting a universal truth or a permanent fact, the tense of the verb in the indirect statement does not change. Since grass being green is a constant fact, the verb 'is' remains in the present tense.

This rule ensures that the statement continues to be understood as something that is always true. Shifting the tense to 'was' would imply that the fact is no longer correct.

✅ Correct Answer: C) Orange is sour when tasted.

📚 Explanation: For sentences involving perception (like taste, smell, or feel), the passive form uses a structure that describes the quality of the object when the action is performed. 'Orange is sour when tasted' is the idiomatic way to express this.

This format focuses on the state of the object during the experience. It is the most natural way to transform sensory verbs into a passive-style description.

✅ Correct Answer: D) cry

📚 Explanation: This sentence describes a general habit or a universal behavior of babies. For such general truths or repeated actions, the simple present tense is used with the base form of the verb.

Since 'Babies' is a plural subject, the verb must be 'cry' to agree with it. This creates a clear and simple statement about a natural human reaction to hunger.

✅ Correct Answer: C) comparable

📚 Explanation: 'Analogous' means that two things are similar in some way and can therefore be compared to each other. It refers to a relationship of likeness or correspondence between different objects or ideas.

The word 'comparable' is the direct synonym because it also describes things that share common features. This term is frequently used in scientific and logical discussions to show patterns.

✅ Correct Answer: C) Daughters-in-law

📚 Explanation: When making a compound noun plural, the 's' is added to the principal or most important word in the phrase. In this case, 'daughter' is the main noun, so the plural form is 'daughters-in-law'.

The hyphenated part 'in-law' stays singular because it acts as a modifier. This rule is consistent for other similar relations, such as brothers-in-law or mothers-in-law.

✅ Correct Answer: A) Disembark

📚 Explanation: The prefix 'dis-' is added to the front of a word to create its opposite meaning. To 'embark' means to go on board a ship or start a journey, so 'disembark' means to leave a ship or aircraft.

This prefix is commonly used in travel terminology to describe the end of a trip. It provides a clear and direct reversal of the original action word.

✅ Correct Answer: B) with

📚 Explanation: The phrasal verb 'cope with' is a fixed expression that means to deal effectively with something difficult. In this sentence, it shows that the person is unable to manage the intense pressure they are feeling.

Adding 'up' after cope is a very common error, as 'cope' alone or 'cope with' is the only correct form. This prepositional pairing is essential for describing how someone handles stress.

✅ Correct Answer: B) Is not honesty the best policy?

📚 Explanation: To convert an affirmative statement into a forceful interrogative, we often use a negative question form. This suggests that the answer is so obvious that everyone already agrees with it.

By asking "Is not honesty the best policy?", the speaker is actually confirming that it is. This is a common rhetorical device used to emphasize a well-known truth or proverb.

✅ Correct Answer: D) Chaste

📚 Explanation: 'Lecherous' is an adjective used to describe someone showing excessive or offensive sexual desire. Its opposite is 'Chaste', which refers to being pure, modest, or refraining from such behavior.

This contrast highlights the difference between unrestrained desire and moral self-control. 'Chaste' is often used to describe a person's character or lifestyle in a positive way.

✅ Correct Answer: C) in

📚 Explanation: The preposition 'in' is used here because 'the shade' is treated as a three-dimensional area or environment that surrounds the people. We sit 'in' the shade just as we sit 'in' a room.

Using 'under' would be appropriate for the tree itself (under the tree), but 'in' is the correct choice for the darkness or coolness created by the tree. This distinguishes between the object and the area it affects.

✅ Correct Answer: B) late

📚 Explanation: The word 'late' can act as both an adjective and an adverb, meaning after the expected time. In this sentence, it describes the time when the person will arrive home.

'Lately' is an entirely different adverb that means 'recently' and would not make sense here. Using 'late' correctly identifies the timing of the journey at the end of the day.

✅ Correct Answer: B) hard

📚 Explanation: In this sentence, 'hard' acts as an adjective describing the difficulty level of the problem. It means the problem was not easy to solve and required a lot of effort.

The word 'hardly' is an adverb that means 'scarcely' or 'almost not', which would change the meaning completely. This choice ensures that the complexity of the task is properly emphasized.

✅ Correct Answer: A) Kolleru Lake

📚 Explanation: Kolleru Lake is one of the largest freshwater lakes in India, situated in Andhra Pradesh between the deltas of the Godavari and Krishna rivers. It acts as a natural flood-balancing reservoir for these two major systems.

The lake is a designated Ramsar site and a critical habitat for many migratory birds. Its location in the fertile deltaic region makes it a unique and important ecosystem in Southern India.

✅ Correct Answer: A) India

✅ Correct Answer: B) Surat

📚 Explanation: The British East India Company established its first permanent factory in Surat in the early 17th century after receiving a royal decree from Emperor Jahangir. Surat served as their primary trading hub on the West coast.

This location provided the English with a strategic foothold for the textile and spice trade. It marked the official beginning of British commercial expansion into the Indian subcontinent.

✅ Correct Answer: B) Maternal uncle

📚 Explanation: Since C and Q are sisters and Z is their mother, Z is also C's mother. P is the son of Z, making P the brother of C. As A is the son of C, P is the brother of A's mother.

In family relations, the brother of one's mother is called the 'maternal uncle'. This logic correctly tracks the bloodlines across two generations to identify the uncle.

✅ Correct Answer: A) Social Reform Act

📚 Explanation: The Native Marriage Act (or Act III of 1872) was a significant social reform law in British India. it legalized inter-caste marriages and set the minimum age for marriage, aiming to curb child marriage.

The act was passed due to the efforts of reformers like Keshab Chandra Sen. it was a major step toward modernizing social laws and providing legal protection for non-traditional marriages.

✅ Correct Answer: D) Philosophy

📚 Explanation: Zoology, Physiology, and Botany are all branches of the natural or biological sciences that deal with the study of living organisms and their functions. They rely on empirical data and experiments.

✅ Correct Answer: C) 39

📚 Explanation: The rule for the first row is simple addition of increasing numbers: 5+4=9, 9+5=14, 14+6=20. The numbers added are 4, 5, and 6.

For the second row, the pattern is: 9+8=17, 17+10=27. Since the added numbers (8, 10) are even and increasing by 2, the next number should be 12. Thus, 27+12=39.

✅ Correct Answer: D) 77%

📚 Explanation: According to the 2011 Census, the average literacy rate in West Bengal was approximately 77.08 percent. This figure was higher than the national average at that time.

✅ Correct Answer: A) Exports Cheaper and Imports Costlier

📚 Explanation: When the value of the rupee falls, it takes fewer dollars for foreigners to buy Indian goods, which makes our exports more affordable and competitive. At the same time, it takes more rupees to buy foreign goods, making imports more expensive.

This economic shift can help domestic manufacturers who sell abroad but may lead to inflation due to higher costs of imported oil and technology. It is a standard result of currency depreciation in international trade.
