The Right Answers

This is an Inference Question, as indicated by "supported by the passage". We need to select the answer choice that can be reasonably implied, given the information in the passage.

A: When mentioning the two theories, the passage states that the "pull mechanism" (pull theory) has long been favoured by MOST scientists. Therefore, we have evidence that the theory has not the UNIVERSALLY accepted, since we know there are some who do not support it.
B: When describing the pull theory in detail, the passage mentions that it relies on a property of water, the ability for water molecules to pull each other. So, we have enough evidence to say that the pull theory depends on one of water's physical properties.

The Wrong Answer

C: This choice has no evidence. We have no information regarding when the push theory originated, so we cannot compare their creation dates.
