Question

1. read the sentences.

original sentences: sir edmund was anxious to explore antarctica. so was his son, cecil.
combined sentence: sir edmund and his son, cecil, were anxious to explore antarctica.
does the combined sentence use a compound subject, compound verb, or compound object?
compound subject
compound verb
compound object

Explanation:

A compound subject is made up of two or more subjects joined by a conjunction (like "and") that share the same verb. In the combined sentence "Sir Edmund and his son, Cecil, were anxious to explore Antarctica", the subjects "Sir Edmund" and "his son, Cecil" are joined by "and" and share the verb "were". A compound verb would involve multiple verbs for one subject, and a compound object would involve multiple objects for a verb, which is not the case here.

Answer:

A. compound subject
