Quote:
B. Incorrect Bermuda Triangle is where the true north and the magnetic north are aligned with each other.
There are two strikes against B:
1. The alignment of true north seems to have happened only in a sliver (small portion of the Bermuda triangle. This would be enough to rule out the answer choice in most cases.
2. Moreover, it seems the passage implies north and magnetic north alignment was happening in the times/days of Columbus but that it does not mean it is still the case today. Weaker reason but nevertheless, the text hints at it
Seems to be a poor-quality question and explanation
A is correct as that is already mentioned in the passage (But although myriad fanciful theories have been proposed regarding the Bermuda Triangle,
none of them prove that mysterious disappearances occur more frequently there than in other well-traveled sections of the ocean. In fact, people navigate the area every day without incident.)
B cant be ruled out either
explanation 1 that you provided, suppose something happened in new york, did it happen in the US. Yes, it did, it did not happen all over the US but it did happen in US.
the option does not mention that the north and magnetic north aligned in entire bermuda triangle, it just says its the place where they aligned.
explanation 2, yes, it's clear from the passage that it isnt necessarily the case that it is still the case today. But the option talks about the case in past tense,
ALIGNED with each other.this Q was in my
gmat club tests and messed up with my head having two clear answers although i got it correct but it was a guess
