which verb best completes sentence 2?
o circle
o circled
o circling
o semi - circle

Explanation:

The sentence is in the past tense as it refers to an event that happened in 1957 (the launch of the first spacecraft). The verb form should be in the past - simple tense. "Circled" is the past - simple form of the verb "circle". "Circle" is the base form (present - simple), "circling" is the present - participle form (used in continuous tenses), and "semi - circle" is a noun (not a verb form).

Answer:

circled
