Answer: His arms muscles work in pairs so that one contracts while the other relaxes as he climbs up.
Explanation: when we exercise one muscle, there is usually another muscle that isn't the target of the exercise but it helps us maintain the form by doing the opposite movement. For example, when we do a bicep curl, the muscle that we are working is the biceps, and it contracts, but at the same time, the triceps relaxes, this is called antagonist muscles. The same thing happens when a rock climber climbs up the rock wall, the biceps contract as he pulls up and the triceps relax at the same time.

Explanation:
Thoreau was a philosopher, a naturalist and author. These propose the things that were significant to him. One of his quotes are, “Rather than love, than money, than fame, give me truth.”A philosopher means a person who is looking for truth. He felt that he needed freedom to follow his study of nature and to have a mind that was able, pure, and unique. So philosophy and independence were two of the many things that were significant to him. He could not rely on completely on wildlife and his own awareness for teaching. Another thing that was significant to him was his writing. He wrote lots of words and his printed writings fill twenty volumes. So this appears that the three things that were significant to him was nature, philosophy, and freedom.
