Instruction: Choose the inference that are clearly supported by the statement.
Statement: All successful candidates for the astronaut training program possess a doctoral degree in a STEM field, and a perfect physical fitness record is also required.
Inferences:
Inference I: A candidate with a doctoral degree in a STEM field who also has a perfect physical fitness record will be selected for the astronaut training program.
Inference II: Achieving a perfect physical fitness record is not sufficient on its own for selection into the astronaut training program.
Show answer & explanation
Correct answer: B
Explanation
The statement gives necessary conditions for selection (doctoral degree in STEM and perfect physical fitness), but does not guarantee selection.
Inference I is incorrect because fulfilling both conditions does not ensure selection.
Inference II is correct because physical fitness alone is not sufficient.
Hence, the correct answer is option 2.
