Correct answer and explanation

Correct answer: as walking

Explanation: Context: The comparison 'uses the same number of calories as...' requires a gerund (verb + ing). Hence, 'as walking' is correct. 1. as walking ✅ – grammatically correct comparison form. 2. than to walk ❌ – wrong comparative connector. 3. than by walking ❌ – incorrect structure. 4. as though you walk ❌ – changes the meaning. Correct Sentence/Example Sentence: Jogging a kilometre uses the same number of calories as walking two kilometres.
