which choice completes the text so that it conforms to the conventions of standard english?

a becomes

b became

c had become

d has become

Explanation:

The sentence is about an event in 1975, which is a specific past time. The simple past tense ("became") is used for actions that happened at a definite time in the past. "Becomes" is present tense, "had become" is past perfect (used to show an action before another past action, which isn't the case here), and "has become" is present perfect (used for actions with present relevance or unfinished actions, not a single past event). So "became" is correct.

Answer:

B. became
