For the first question, a person would weigh less on Mercury than they do on Earth due to the lower gravity. For the second question, the statement about hypotheses being tested with experiments is True, as it's a fundamental aspect of the scientific method.
The main answer to the first question, regarding the weight of a person on Earth compared to Mercury, is [B] False. The weight of an object is calculated by multiplying its mass by the acceleration due to gravity. Since Mercury has only about 38% the surface gravity of Earth, a person would actually weigh less there compared to Earth, not more.
Coming to the second question, a hypothesis being tested by designing and conducting experiments. The main answer here is [B] True. In the scientific method, hypotheses are indeed validated or refuted based on the results of experiments conducted to test them.
In conclusion, the weight of an individual would be less on Mercury than on Earth, and hypotheses are indeed tested by conducting experiments.
