Which of the following sentences demonstrates proper subject-verb agreement? a) Physics is a difficult subject to learn. b) Measles usually spread through respiratory fluids. c) The study of various sciences are compelling. d) News travel fast

What do you think?

The sentence that demonstrates proper subject-verb agreement is:

a) Physics is a difficult subject to learn.

In this sentence, the subject "Physics" is singular, and the verb "is" agrees with the singular subject.

The correct sentence that demonstrates proper subject-verb agreement is:

a) Physics is a difficult subject to learn.

To determine the correct sentence, we need to ensure that the subject and the verb agree in number. In this case, the subject "Physics" is a singular noun, so it should be paired with the singular verb "is."

Let's analyze the other options:

b) Measles usually spread through respiratory fluids.

In this sentence, "Measles" is a plural noun, so it should be paired with the plural verb "spread."

c) The study of various sciences are compelling.

In this sentence, there is a subject-verb disagreement. "The study" is a singular noun, so it should be paired with the singular verb "is" instead of "are."

d) News travel fast.

In this sentence, there is also a subject-verb disagreement. "News" is an uncountable noun, which is typically treated as singular. Therefore, it should be paired with the singular verb "travels."

To summarize, the correct sentence that demonstrates proper subject-verb agreement is: "a) Physics is a difficult subject to learn."
