Each problem consists of three statements. Based on the first two statements, the third statement may be true, false, or uncertain.Battery X lasts longer than Battery Y.Battery Y doesn't last as long as Battery Z.Battery Z lasts longer than Battery X.If the first two statements are true, the third statement is:
Correct answer: C. Uncertain
- A. True
- B. False
- C. Uncertain
- D. None of these
Explanation
The first two statements establish that Battery Y has the shortest lifespan. However, they do not provide a direct comparison between Battery Z and Battery X. Therefore, it is uncertain if Battery Z lasts longer than Battery X, making the third statement uncertain. Options A and B are incorrect because they assume a certainty in the relationship that is not supported by the provided information.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
