Which choice completes the text so that it conforms to the conventions of Standard English?
Explanation
Choice A is the best answer. The convention being tested is subject-verb agreement. The singular verb "occurs" agrees in number with the singular subject "radiation."
Choice B is incorrect because the plural verb "have occurred" doesn’t agree in number with the singular subject "radiation." Choice C is incorrect because the plural verb "occur" doesn’t agree in number with the singular subject "radiation." Choice D is incorrect because the plural verb "are occurring" doesn’t agree in number with the singular subject "radiation."
