Can I have a bit of clarification? I don't completely understand.
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!
The correct answer is B. Review your results
When you review your results you can see whether or not they fit your hypothesis and if it failed then you can reformulate it to create a new hypothesis and start new research. You can also see whether something doesn't fit or if you made a mistake.

The very first part “The students completed the math assignment” is not parallel with its other parts. Since the other sentences discuss either English or words/terms, it wouldn’t be a good idea to add the first sentence in this.
