Question

Choose the correct modal. 
Some people _____ ski better than others.

Accepted Answer

1. Explanation for Option 2 ("can"):

The modal verb "can" is used to express ability or capability. In the sentence "Some people can ski better than others," the use of "can" indicates that certain individuals possess the skill or ability to ski more proficiently than others. This is the most appropriate choice because the sentence is discussing the varying levels of skill among people, and "can" directly relates to their ability to perform the action of skiing.

2. Explanation for why the other options are incorrect:

- Option 1 ("must"): The modal verb "must" is typically used to express necessity or obligation. If we were to use "must" in the sentence, it would imply that it is necessary for some people to ski better than others, which does not logically fit the context of discussing ability or skill.

- Option 3 ("could"): "Could" is often used to indicate past ability or a possibility in the present or future. While "could" can sometimes relate to ability, it is not as direct as "can" when discussing current skills. In this context, "could" would imply a potential or hypothetical ability rather than a definite one.

- Option 4 ("should"): "Should" is used to express advice, recommendation, or expectation. Using "should" in the sentence would suggest that it is advisable or expected for some people to ski better than others, which does not align with the intended meaning of discussing actual ability.

In conclusion, "can" is the correct modal verb to use in this context because it accurately conveys the idea of some people having the ability to ski better than others.
