While the singular verb "was" is next to the singular noun "organization," the subject of the sentence is the plural noun "bylaws." This means that the verb "was" needs to be changed to a plural form; therefore, "The new bylaws of the organization were" is the correct answer choice.

The answer choice "the distance between the sun and the planets varies over time" is correct. It correctly uses a singular verb—"varies"—to match the singular subject, "distance."

Do not make the mistake of deciding to eliminate either ‘because’ or ‘in that’ – both are more or less the same, and they are not what is being tested. The main problem with the sentence is that suddenly the single squid has become a multitude. Thus you can immediately eliminate those containing "these creatures". You can also eliminate the phrase which changes the meaning and makes the squid one of the most enormous of all living creatures. Finally, we are talking about the creature in its natural environment and so the vague ‘a natural environment’ is not appropriate.
