What is the most logical and rational inference that can be made from the above passage?
Answer & explanation
Answer: (d) There is no perfect diet or one solution for obesity.
People differ in genetics, age, health, lifestyle and the foods they tolerate, so the passage says so many complexities cannot be reduced to one diet — which is why diets fail to curb obesity. The inference: no perfect diet, no single solution.
- ✗ (a) The passage calls dieting an epidemic, not obesity; the option swaps the subject.
- ✗ (b) That everyone seeks a perfect body is the passage's opening observation, not the inference its argument leads to.
- ✗ (c) Diets fail unless causes are addressed and habits change — which implies obesity can be tackled, not that it is incurable.
- ✓ (d) 'we really cannot reduce so many complexities into one diet or diet book' — no single diet suits everyone.
Remember · The inference is where the argument lands, not a restated opening line; also watch for options that swap the passage's subject.
