I have trouble completing sentences for selecting the right word for the sentence.
The answer to question 27 is (c) why not a?
The answer of this 28 (c) Why?

The results of the study are intriguing but a few major pieces of the puzzle are still missing. If members of the team 27. (a will manage – b would manage – c managed) to pin down where and when wind changes occur, it would be easier to prove that they 28. (a connect – b are connecting - c are connected) to the ultraviolet fluctuations. Filling in those pieces could pay dividends by improving predictions of when and how the rotation rate will change. These) are important when using Earth-based radio dishes to track spacecraft.

I would be happy if you could give me words that directed you to the right answer.
And tips for a solution

Answer

Hi! There are two massive grammar topics here in your sentences. I'd recommend you to check some extra sources for them. 
But briefly as for 27, the sentence uses the 2nd Conditional whose scheme is 1) Past Simple in the if-part and 2) "would + Infinitive of the verb" in the main part of the sentence.
e.g. I would help you if you asked me.
e.g. If I were you, I would never take part in this competition.
As for 28, the Grammar rule is called Passive voice. According to the text, these ultraviolet fluctuations and wind changes have some connection. Thus we say that "they are connected". For Passive we use "to be + V3". You use "to be" in the necessary tense and form and always use the third form of the verb after it.
e.g. These topics are connected so we will discuss them both during the next meeting.
e.g. My father is invited to this party every year.
e.g. The house was built a month ago.
e.g. Urgent measures must be taken.
