Answer:
The correct answer is A. Louise will be swimming, biking and running for her triathlon this weekend.
Explanation:
A parallel sentence is a sentence that uses the same form of a word throughout. In the sentence above, all verbs are used in their future progressive tense: <em>will be swimming, (will be) biking, (will be) running. </em>Therefore, their form is the same, and thus the sentence is parallel.
Sentence B is incorrect because different forms of the verbs are used: <em>will be swimming, bike, run - </em>as you can see, they're not the same.
A drawback occurred in the melody because of a miscommunication in the counterpoint. I think that's ok ?
Think of an equation:
200 - 91 = 109
You can do anything to this equation, as long as you do the same thing to both sides. So, if you add 91 to both sides, you will get:
200 = 200
Since this holds true, Susan's strategy to add her answer to 91 makes sense.
