Which choice completes the text so that it conforms to the conventions of Standard English?
Explanation
Choice D is the best answer. The convention being tested is subject-verb agreement. The plural verb "were" agrees in number with the plural subject "ayllus," which are described as plural "family clans."
Choice A is incorrect because the singular verb "is" doesn’t agree in number with the plural subject "ayllus." Choice B is incorrect because the singular verb "was" doesn’t agree in number with the plural subject "ayllus." Choice C is incorrect because the singular verb "has been" doesn’t agree in number with the plural subject "ayllus."
