Read each sentence to find out grammatical error or errors in idiomatic expressions in it. The error will be in one part of the sentence. The number of that part is the answer: At 21, (1)/ she, in many ways, (2)/ is like any girl (3)/ to her age. (4)

Correct answer: 4

Explanation: Context: The preposition ‘to’ in ‘to her age’ is incorrect. When comparing people of the same age, the correct preposition is ‘of’. So the correct answer is option C. 4 1. At 21 ✅ – correct phrase. 2. she, in many ways, ✅ – correct structure. 3. is like any girl ✅ – correct usage. 4. to her age ❌ – incorrect; should be ‘of her age’. Correct Sentence/Example Sentence: At 21, she, in many ways, is like any girl of her age.
