A:There are two companies, H and C, that run their business in a location. H just moved in where C used to do business. H is successful since it's planning to open a new outlet in a near city. C faced a decreasing service or product at a new site. So the place that H is currently running business, or where C used to do so, is a great business business.
I: People tends to accept those who can successfully demonstrate their skills in tasks that they expect other to do as leader.
Math: jj并不多,8,9道吧, 其他不难算 一道DS图形题: 图中有一段开口朝下 trajectory 是小球划、弹过的痕迹, 问能否算出此 trajectory 长度(弧长) (1)最高点离地面30feet (2)告知着地点和起跳点之间的距离
是否能判断IxyI+xy<=0 (1)IyI+xy<=0 (2)IxI+xy<=0
K*K>4, K<0, 1/k range?
CR: 狗比狼更易与人进行互动,social,即便是刚出生不久的小狗。结论是狗经过进化已经把这种习性基因化,内置了。 问:这是based on什么假设 我选的:看刚出生的还从未与人接触过的小狗能否与人social

关于在一种蜜蜂化石的身上发现了兰花花粉的化石,以致把此兰花的灭绝时间进一步精确。最后因为这段精确后的时期和恐龙存活期正好一至,从而可揣测和此兰花相比,恐龙的灭绝原因。
一个前苏联科学家综合了其前辈苏联科学家关于自然进化论的观点,提出了自己的观点。当是苏联以外的主流还是自然选择。他其实就是综合了一下。
希望还有点用。
