Students at some schools choose their classes. Every student has a different schedule. For example, one student is holding a flute case. He is going to his music class. At the same time, another student is carrying her gym shoes for P.E. class.

It is often thought that when humans first learned how to control fire, one of the major effects was to keep people warm. However, this wrongly implies that our pre-cooking ancestors would have had difficulty staying warm without fire. Chimpanzees can survive nights while exposed to long, cold rainstorms, whereas gorillas sleep uncovered in high, cool mountains. Humans and every other species can maintain body heat without fire. This would mean our ancestors did not first control fire for warmth.

Still, the opportunity to be warmed by fire created many options. Humans are far better than chimpanzees and gorillas at running long distances. The problem with most animals is that they easily overheat when they run. They cannot develop a solution to this problem; animals need something to maintain body heat during rest or sleep, such as a thick coat of hair. They, unlike humans, are unable to remove this after exercise.

Carrying a box of sugar cubes in hand, the host rushed back from his inner room after hearing the crash of the thermos. Seeing the hot steam, he cried out, “It doesn’t matter!” but the father muttered, “Sorry, I touched it and it fell.”

When they left the house, the daughter asked her father if he had touched the thermos. He replied , ” no, but it stood close to him. ” His daughter then said that she did not see him touch it, as she could see his reflection in the mirror. When he asked his daughter what caused its fall, she explained, “The thermos fell by itself. The floor is uneven. It wasn’t steady when Mr. Li put it there.” She then questioned why he took the blame.

“There are things which people accept less the more you defend them,” the father responded. “The truer the story you tell is, the less true it sounds.”
