Question

Which is different?












Question 2
Find “both” answers.

The answer to the question chosen is (answer)
units. The answer to the three questions not chosen is (answer)
square units.

Answer 1

As we can see from the condition, the difference is in the units, logic and semantics (meaning).

The first statement: 'The answer to the question chosen is (answer) units' contains units (for instance, meters or miles), while the other: 'The answer to the three questions not chosen is (answer) square units' contains square units, which can be square meters ($\text{m}^2$) or square miles ($\text{mi}^2$). The first example may describe length, the second example describes area, a different characteristic. However, in this situation there might be a dependence of the following form:

$$\text{area}=\text{length}^2.$$

Besides, the statements are different logically and semantically: the first one is a statement speaking about only one question while the other is a negation speaking about three questions.
