Question

What change, if any, should be made to this sentence?
A.
No change is necessary.
B.
Change lives to life.
C.
Change causes to cause.
D.
Change endanger to endangers.

Answer 1

The correct choice is: C. Change causes to cause.

The sentence should read: "Bacteria, such as Streptococcus pneumoniae and Heliobacter pylori, cause infections in humans and other organisms, and bacterial infections endanger the lives of many people around the world."

This is because "bacteria" is a plural noun, so it should be followed by the plural verb "cause" instead of the singular "causes."
