In what way does pheromone work on the same species of plant or animal? [br]
We’ve now had a way of working on insects to change their behavior with how to stop locusts swarming, and a possible way of changing crops to help them survive a drought. Now here’s an ingenious piece of research that tries to do both at the same time. To control insect activity and help the crop grows through one treatment. It’s all down to pheromones, the chemical signals that allow members of the same species of plant or animal to communicate. They’re as powerful as hormones, which travel in the blood, but unlike hormones they travel through the air. And it’s the 50th birthday of their discovery this year.
The French President Nicolas Sarkozy says the gunman responsible for the murders of a teacher and three children at a school in Toulouse was the same one that killed three soldiers in similar incidents last week. In a nationwide television broadcast, Mr. Sarkozy said the same weapon was used each time. French police also believe the same vehicle was used. Chris Bockman, a journalist who’s in Toulouse, says similarities between the attacks have been clear from the start.
选项
A、Because he was asserted to use the same weapon in two incidents.
B、Because some witnesses claimed that he committed these killings.
C、Because the police confirmed that the vehicle he used had been found.
答案
A
解析
总统萨科齐说两次谋杀案的凶器相同,而警察猜测凶手的vehicle也相同,只是猜测并未证实。所以答案为A。
