问题     NASA chief Charles Bolden vowed to produce a detailed plan to develop the technology needed to get astronauts to Mars after lawmakers blasted the agency’s lack of clear goals at a congressional hearing on Wednesday. On 1 February, Bolden announced the president’s intention to cancel the Constellation programme, which was tasked with developing rockets and other hardware to return humans to the moon.
    In the agency’s proposed 2011 budget, the White House did not specify where NASA would go but funded work on new technologies for space flight and encouraged the development of commercial space taxis to transport astronauts to the International Space Station. The new plan faced criticism from lawmakers on Wednesday at a hearing of the US Senate’s Science and Space subcommittee—Bolden’s first congressional hearing since the plan was announced.
    Subcommittee chairman Bill Nelson of Florida said the proposal "gave the perception that the president was killing the manned space programme" and left the agency’s new goals unclear. "The president, either himself or through the NASA administrator needs to clearly state what the goal is," he said.
    Nelson did not reject the new plan outright, pointing to "more positive things" within it, such as the funding boost for technology research and development. But he said he is concerned that there is relatively little money available in the new budget to develop a powerful "heavy-lift" rocket needed to send astronauts beyond low-Earth orbit.
    In response, Bolden referred to the possibility of setting up fuel depots (仓库) in orbit, which could enable smaller rockets to make trips beyond low-Earth orbit. But he also said the agency may eventually ramp up its investments in more powerful rockets. "There will come a time when I will ask for more money on heavy lift," he said.
    The new plan is just a proposal so far. It will be implemented only if Congress votes to approve the budget requested by the White House. Getting that approval will be a challenge. Subcommittee member David Vitter of Louisiana said he would fight "with every ounce of energy I have" against the plan. Bolden is scheduled to appear before a committee of the US House of Representatives on Thursday. [br] According to Nelson, what’s the good aspect of the new plan?

选项 A、It will deal with sending astronauts around low-Earth orbit.
B、It will deal with sending astronauts to Mars.
C、It can set up fuel depots in orbit.
D、It will provide money for technology research and development.

答案 D

解析 细节辨认题。由定位句可知,Nelson没有完全反对这个新计划,指出里面有“更积极的东西”,如为促进技术研究和发展提供资金,因此Nelson认为该计划中比较好的一方面就是为技术研究和发展提供资金,故D)“它会为技术研究和发展提供资金”与文意相符,为正确答案。
