Final answer:
To create compound sentences from the provided examples, coordinating conjunctions like 'and', 'but', or 'so' are used to join the separate sentences into one. Each new sentence connects the ideas from the original pairs of sentences into a single cohesive statement.
Step-by-step explanation:
To convert the given sentences into compound sentences, conjunctions such as 'and', 'but', or 'so' can be used to join the two independent clauses.
- The boy laughed, and the girl giggled.
- The brown squirrel ran up the tree, but the dog did not bark.
- Julie wanted a piece of cake, but her mom said no.
- It was bedtime, yet it was still daylight.
Compound sentences combine two independent clauses with a coordinator and a comma or just with a semicolon (if the sentences are closely related in theme).
