Final answer:
The sentence implies that giant squids are found globally but are rare in tropical and Arctic waters, without giving an explicit reason for this distribution pattern. Therefore, options a), b), and d) are incorrect. As the sentence doesn't provide an explicit reason for their preference, option c) is also incorrect.
Step-by-step explanation:
The sentence "The giant squid lives in all of the world's oceans—though few are found in the tropics or the Arctic waters." conveys specific information about the distribution of the giant squid. It tells the reader that while giant squids can be found globally, their presence is scarce in tropical and Arctic regions.
This piece of information neither explicitly states the reason for their distribution pattern, nor does it suggest that the absence of studies in the Arctic regions is the cause.
Therefore, options a), b), and d) are incorrect. As the sentence doesn't provide an explicit reason for their preference, option c) is also incorrect. The correct interpretation of the sentence lies outside the provided choices, as it implies a broad distribution with specific environmental preferences that exclude extreme temperatures.
The sentence tells the reader that the giant squid lives in all of the world's oceans, but it is less commonly found in the tropics or the Arctic waters. This information suggests that the giant squid may have a preference for waters that are not too hot or too cold. However, it does not explicitly state the reason for this preference.
Therefore, options a), b), and d) are incorrect. As the sentence doesn't provide an explicit reason for their preference, option c) is also incorrect.
