GMATNinja KarishmaBI have doubt in Q6. Which of the following, if true, would most strengthen the hypothesis mentioned in lines 17-19 [Such evidence is consistent with researchers’ hypothesis that anteaters use electroreceptors to detect electrical signals given off by prey]?
Option B. Researchers are able to detect a weak electrical signal emanating from the nesting chamber of an ant colony.
In strengthen questions, we never go against facts. When it is given in passage that researchers as yet have been unable to detect electrical signals emanating from termite mounds, then why is option B correct? It is going against the fact. Isn't it?
The passage says "researchers
as yet have been unable to detect electrical signals emanating from termite mounds, where the favorite food of anteaters live. "
So researchers have not been able to detect them as yet.
But which of the following if true will make the hypothesis more likely? If the researchers are able to detect it, then the hypothesis will become more likely.
Note that the passage does not say "termite mounds do not emanate electrical signals." It only says that the researchers have been unable to detect them YET. If they are able to detect them, then it doesn't contradict the passage.
