Question

Which sentence uses the compound sentence comma correctly?
Bill drew me a map, yet I couldn't find his house.
Bill drew me a map yet, I couldn't find his house.
Bill drew me a map yet I couldn't find his house.

Answer 1

the second option

hope this helps :)

Answer 2

The question should say complex, because 'yet' is being used, but whatever. xD

The answer is "Bill drew me a map, yet I couldn't find his house."

The ',' separates "Bill drew me a map" and  "I couldn't find his house", and without it, the sentence would be a run-on.
