Hey there!
<span>Use the past participle of the verb do to complete the following sentence. The stranger _____ this town a great service.
Answer: D has done!
:)
</span>
The word (yet) is the coordinating conjunction
I believe the answer is B.
The correct answer would be 3, gasta as you are conjugating the verb "gastar" for ella as the word "hermana" means sister and is feminine.
Source(s): I speak Spanish. :)
Hope this helped; have a great day!
