<u>Answer</u>:
Out of the following sentences, the one that uses dashes correctly is - "The New Zealand Papua New Guinea handball team's stars Fredrickson, lacho, Honey, and Ipatas, have all demonstrated - hey, what's that duck doing here? Here, the right answer is Option B.
<u>Explanation</u>:
There is a surprise element at the end of the sentence which is marked by an exclamation ‘hey’ and a question. So, the dash is placed after the verb ‘demonstrated’ to highlight this surprise element of the sentence.
Also, the dash is used to emphasise on the conclusion or introduction of the sentence. Over here it gives importance to the conclusion of the sentence. Plus, it helps in breaking up the dialogue here.
Option B, Down
Mom has to descend the basement stairs.
You can get rid of <em>down</em>, because the word <em>descend</em> means to go down.
