Question 2

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

By referencing 'other areas near the North Sea,' the author aims to challenge the validity of the explanation being discussed, suggesting that the circumstances in those regions may not align with the proposed theory.

A) propose a new hypothesis

This option is incorrect because the mention of 'other areas near the North Sea' does not introduce a new hypothesis but rather questions the existing explanation. The focus is on casting doubt rather than proposing an alternative theory.

B) anticipate a possible objection

While anticipating objections can be a part of the discourse, this option does not accurately reflect the author's intent in the context provided. The author is not merely preparing for objections but is actively questioning the explanation's robustness.

C) cast doubt on a particular explanation

This option is correct as the author uses the reference to 'other areas near the North Sea' to highlight inconsistencies or shortcomings in the explanation being examined. This serves to undermine the credibility of the explanation rather than reinforce it.

D) point out an ambiguity in an argument

This option is incorrect because the author's intent is not to identify ambiguities but to directly challenge the explanation's validity. The focus is on doubt rather than ambiguity in the argument itself.

Conclusion

The correct answer is definitive as the author's mention of 'other areas near the North Sea' serves to question and cast doubt on the explanation rather than propose new ideas or merely prepare for objections. All other options fail to capture the essence of the author's argument and the specific role of the reference in the text.
