单选题When might you need to give blood for a personality (个性) test? The answer is that you need to do so when you ask for a job. Some people believe that your blood group hides no secrets. It shows the" real you". And the owners of certain blood groups might be particularly good or bad at certain tasks. This is the very reason why you could be asked to offer your blood group before being given a job. The new idea was carried out first in Japan and now it had been brought over to other parts of the world. One important business company in Japan is quite special about its needs: "For our office members, we must have 30 percent of group A and 15 percent of AB, 25 percent of O and 30 percent of B. Do you happen to know your own blood groups? It seems that if you belong to blood group O, you can get things done and sell the goods well. Blood group A are the thinkers, while blood group B are highly creative (创造力的). And if you have problems, ask the ABs to solve them. So if you visited the Japanese company, you would find the O types out selling goods and A types keeping orders in the office.
