Finding the full and correct question that you are asking here, I find this, and the answers: The team attacked but couldn´t score a goal. Then, through a/an ___ ordinary piece of good fortune, the other team accidentally kicked the ball into the wrong goal. The two options to fill in the blanks would be: extra and counter.

Thus, the correct way to fill in the blanks in this question, given the context of the sentences and the structure, as well as the meaning of the words to be used, would be:

The team counter attacked but couldn´t score a goal. Then, through a/an extraordinary piece of good fortune, the other team accidentally kicked the ball into the wrong goal.

quite an interesting way to teach topic sentences, because the answer to this question is the best definition of a topic sentence that one can present, it is as if answering the questions taught you how to do it, this is some real teaching, it is terribly well-done.

the topic sentence in this paragraph is:

topic sentences writers stay on track and keep a paragraph from becoming an aimless collection of sentences about an idea.

which incidentally tells you what a topic sentence should be.

this doesnt make any sense imao
