Question

they harnessed luna and nanuk to their small sled and took off. the clear blue sky gave edgar hope that they would make good time.
but seemingly out of nowhere, a light snow started falling, and the wind began to pick up. before long, the boys could hardly see the dogs in front of them, much less the path. everything was white!
a sudden gust tipped them over into a snowdrift. alaskas fickle weather had brought them to a halt.
the boys huddled with luna and nanuk in the snowbank. all they could do was wait and hope the storm would pass quickly.
look at the word in bold. what happened to bring the dogsled to a halt? use context clues in nearby text to help you figure out the meaning of the word fickle.
the weather was unusual for winter in alaska.
the weather changed suddenly.
the weather was too foggy to see.
the weather was stormy all day long.

Explanation:

The text first notes a clear blue sky, then suddenly a light snow, strong wind, and a gust that tipped the sled. This sudden shift from clear to stormy shows the weather is "fickle" (changing quickly unexpectedly). The other options don't match: the text doesn't say it's unusual for Alaska winter, it wasn't foggy, and it wasn't stormy all day.

Answer:

The weather changed suddenly.
