If you are like most people,your intelligence varies from season to season．You are probably a lot sharper in the spring than you are at any other time of the year．A noted scientist,Ellsworth Huntington(1876-1947),concluded from other men's work and his own among peoples in different climates that climate and temperature have a definite effect on our mental abilities.
He found that cool weather is much more favorable for creative thinking than is summer heat．This does not mean that all people are less intelligent in the summer than they are during the rest of the year．It does mean,however,that the mental abilities of large numbers of people tend to be lowest in the summer.
Spring appears to be the best period of the year for thinking．One reason may be that in the spring man's mental abilities are affected by the same factors that bring about great changes in all nature.
Fall is the next-best season,then winter．As for summer,it seems to be a good time to take a long vacation from thinking!

According to the passage,any vacations from thinking should be taken__.

A.several times throughout the year
B.during spring and fall
C.during the summer
D.as seldom as possible
