问题    The government of Burkina Faso granted scientists permission to release genetically engineered mosquitoes anytime this year or next, researchers announced Wednesday. It’s a key step in the broader efforts to use bioengineering to eliminate malaria in the region.
   The release, which scientists are hoping to execute this month, will be the first time that any genetically engineered animal is released into the wild in Africa. While these particular mosquitoes won’t have any mutations (变异) related to malaria transmission, researchers are hoping their release, and the work that led up to it, will help improve the perception of the research and trust in the science among regulators and locals alike.
   In Africa, the project’s success depends on more than just the science of genetic engineering. The people who live in the areas where the mosquitoes will be released must give their consent, researchers must staff and maintain labs to work with genetically modified animals, and regulators must accept the new technology. The impending (即将发生的) release of these mosquitoes serves as a stress test for the whole system.
   These mosquitoes, unlike their "gene drive" counterparts, are not intended to have a lasting impact on the insect population. They have something called a "sterile (不育的) male" mutation—none of the male mosquitoes that will be released will be able to have offspring. Nearly all will be male, but less than one percent might be female—which are the only members of the species that bite. If any bite a human, they will not pass on any genetically modified material. All of the modified mosquitoes the group will release are also weaker than natural mosquitoes, so they should die off in a matter of months.
   The scientists also worked hard to address questions about the science behind their efforts—including concerns about whether those "sterile males" might somehow pass on that sterile status to humans. And they even brought in linguists and worked with the village’s residents to develop a standard vocabulary of scientific phrases in Dioula, the local language, which doesn’t have words for ideas like "gene".
What does the author say about the project?
选项 A、There are some problems behind it.
B、Cooperation is needed for its success.
C、It is under great pressure.
D、Regulators’ consent and acceptance are essential.
答案B
解析 推理判断题。由定位句可知，在非洲，该项目的成功不仅仅取决于基因工程科学。研究人员必须征得生活在蚊子释放区域人们的同意，配备人员并维持实验室的工作，以进行与转基因动物相关的工作，而监管机构必须接受这一新技术，可见这项工程需要多方合作，故答案为B)。A)“工程还存在一些问题”，第五段第一句指出科学家们还将努力解决他们所做努力背后的一些科学问题，并不是该工程本身存在问题，故排除该项；C)“工程顶着巨大压力”，文中并没有提到相关内容，故排除；D)“监管机构的许可和接受非常重要”，由定位句可知，研究人员必须征得生活在蚊子释放区域人们的同意，监管机构必须接受这一新技术，该项与原文表述不一致，故排除。
