Most able-bodied people would struggle with climbing Mt. Kilimanjaro (only 50% of the people who attempt to climb the 19,541 ft tall mountain make it to the top). For double-amputee Spencer West, the climb was especially challenging. After 7 days of hiking, West made it to the top using only his hands. In addition to being the first person to climb Mt. Kilimanjaro on his hands, West also raised almost $500,000 that he plans to donate to charity. You can read more about his incredible climb here.

You should always remember to make a prediction before you look at the answer choices. All of the information that you need to choose the correct answer is given in the sentence.

As always, look for clues in the sentence to help you predict a word for the blank. You know that "Currently rising temperatures . . . are ___________ of a still warmer world . . . ."

Now, take a look at the answers and see which one matches your prediction.
Only (B) matches your prediction. (E) and (C) could have been tempting if you hadn't made a prediction . (A) and (D) just don't work in the sentence as it is.
