6月初，9月份某期货合约价格为17500元/手，11月合约价格为17550元/手，前一合约价格比后者低50元。套利者根据历年6月初的9月份合约和11月份合约问的价差分析，认为9月份合约的价格较低，或则11月份合约价格较高，价差大于正常年份的水平，如果市场运行正常，这二者之间的价差会恢复正常。该套利者应该如何操作？如果到7月底，(1)9月期价为17530元/手，11月期价为17570元/手；(2)9月期价为17480元/手，11月期价为17540元/手；套利者平仓出来后交易结果如何？

Before considering this question it is interesting to review briefly the evolution of 【M1】
the mind as the instrument. The commonest way that has been used to find out the
relative intellectual level of creatures at different stage
of evolutionary complexity has 【M2】
been to study the way they behave when giving different kinds of puzzles. For example, 【M3】
an ant possesses a complex routine of behaviour, but can it think？ The answer is what 【M4】
if an ant is forced to go through a maze of passages, many of which are dead ends,
on its way to its nestle, it starts by making a lot of mistakes and taking a great many 【M5】
wrong turnings. In the end, however, after it has to worry its way through often 【M6】
enough, it does learn to get to its nest without going into any of the blind alleys.
As one moves up the evolutionary scale the test of mind-power exemplified by solving 【M7】
the problem of getting through a maze becomes very simple. Among mammals, 【M8】
for example, the maze is an inadequate test. The learning problem does not tax enough
attributes of the mind. In this sort of learning, as a matter of fact, rats can hit university
undergraduates and have, in fact, repeatedly done so. The next, more subtle test of 【M9】
mental ability is to see what level an animal can think about something when 【M10】
it is not there.
