The correct answer is:
<span>[O say what stranger cause, yet unexplor'd,
Could make a gentle Belle reject a Lord?]
The poet is wondering why a girl would ever reject a man who is hitting on her and wants to marry her. It is implied that women had no say in this - that their marriage depended solely on the man and that they couldn't choose at all. The entire poem is quite satirical and meant to mock these kinds of ideas and behaviors.

The reader is introduced to the marlin because Santiago sees one of the projecting sticks dip in the water (B).
In <em>The Old Man and the Sea</em>, the main character becomes aware of the presence of the marlin when he realizes something is tugging at his hundred-fathom-deep fishing line. Because of the strength of the bite, the stick to which the line is attached is pulled into the water. Santiago immediately recognizes the fish as being a large marlin.
The right answer is alternative four.
In the excerpt from "A Relay Race to Remember," the expression "he was gliding through the water like a dolphin" injects surprise into the story by making a comparison between that conveys how well Sean performs in he race. The phrase describes that Sean swims as well as a dolphin, meaning that he executes brilliantly at the race.
The rest of the options are not correct because the remark does not develop Malik's character or depicts how he swims, and it is not the end of the story.
