Question 22

The author mentions 'other areas near the North Sea' primarily to cast doubt on a particular explanation.

By referring to 'other areas near the North Sea,' the author aims to challenge the validity of a specific explanation, suggesting that conditions or factors in these areas may not align with the presented argument.

A) propose a new hypothesis

This option is incorrect because the author is not introducing a new hypothesis; rather, they are questioning the existing explanation by highlighting inconsistencies with other regions.

B) anticipate a possible objection

While this option might seem relevant, it is not the primary purpose. The mention of other areas serves more to undermine the original explanation than to prepare for counterarguments.

C) cast doubt on a particular explanation

This option is correct as the author uses the reference to other areas to undermine the credibility of the explanation given. By doing so, they indicate that the explanation may not be universally applicable.

D) point out an ambiguity in an argument

This choice is incorrect because the author does not highlight ambiguity. Instead, they directly challenge the validity of the argument by referencing additional locations that may contradict the explanation.

Conclusion

The mention of 'other areas near the North Sea' effectively casts doubt on the particular explanation by suggesting that it may not hold true across different contexts. In contrast, the other options either misinterpret the author's intent or fail to address the core function of the reference. Thus, Option C stands out as the most accurate interpretation of the author's purpose.
