What is the benefit of asking questions with no ready answers?

A．It arouses students' interest in things around them.
B．It cultivates students' ability to make scientific inquiries.
C．It trains students' ability to design scientific experiments.
D．It helps students realize not every question has an answer.

参考答案B

解析:
定位。根据题干中的benefit of asking questions和no ready answers定位到文章第三段第三句：Wefound that when we taught participants to ask“What if?”and“How can?”questions that nobodypresent would know the answer to and that would spark exploration，they engaged in better inquiry atthe next exhibit--asking more questions，performing more experiments and malting betterinterpretations of their results.
详解.推理判断题。定位句指出，当教学员提出“如果?”和“如何?”这些现场没有人知道答案但又会激发其探索欲的问题时，学员们在下次展览时会进行更好的探究——提出更多的问题，进行更多的实验并对其研究结果做出更好的解释，由此可知，提出没有现成答案的问题，其好处是培养了学生们进行科学探究的能力，故答案为B)。
点睛.A)“它引起了学生们对身边事物的兴趣”，定位句只提到这些问题会激发其探索欲，但没有提到会引起学生们对身边事物的兴趣，故排除；C)“它培养了学生们设计科学实验的能力”，定位句只提到学生们会进行更多的实验，但没有提到学生们设计科学实验，故排除；D)“它帮助学生们意识到并非所有的问题都有答案”，定位句提到的是教学生们提出没有人知道答案的问题，但并没有指出这会帮助学生们意识到并非所有的问题都有答案，故排除。

Questionsare based on the following passage.
"There's an old saying in the space world: amateurs talk about technology, professionals talkabout insurance." In an interview last year with The Economist, George Whitesides, chief executive ofspace-tourism fu'm Virgin Galactic, was placing his company in the latter category.But insurance willbe cold comfort following the failure on October 31st of VSS Enterprise, resulting in the death of onepilot and the severe injury to another.
On top of the tragic loss of life, the accident in California will cast a long shadow over the future of space tourism, even before it has properly begun.
The notion of space tourism took hold in 2001 with a $ 20 million flight aboard a Russianspacecraft by Dennis Tito, a millionaire engineer with an adventurous streak.Just haft a dozen holiday-makers have reached orbit since then, for similarly astronomical price tags. But more recently,companies have begun to plan more affordable "suborbital" flights--briefer ventures just to the edge ofspace's vast darkness.Virgin Galactic had, prior to this week's accident, seemed closest to startingregular flights.The company has already taken deposits from around 800 would-be space tourists,including Stephen Hawking.
After being dogged by technical delays for years, Sir Richard Branson, Virgin Galactic's founder,had recently suggested that a SpaceShipTwo craft would carry its first paying customers as soon asFebruary 2015. That now seems an impossible timeline. In July, a sister craft of the crashedspaceplane was reported to be about half-finished.The other half will have to walt, as authorities ofAmerica's Federal Aviation Administration (FAA.and National Transportation Safety Board work out:what went wrong.
In the meantime, the entire space tourism industry will be on tenterhooks (坐立不安 ).The 2004Commercial Space Launch Amendments Act, intended to encourage private space vehicles andservices, prohibits the transportation secretary (and thereby the FAA.from regulating the design oroperation of private spacecraft, unless they have resulted in a serious or fatal injury to crew or.passengers.That means that the FAA could suspend Virgin Galactic's licence to fly.It could also insiston checking private manned spacecraft as thoroughly as it does commercial aircraft.While that may:make suborbital travel safer, it would add significant cost and complexity to an emerging industry thathas until now operated largely as the playground of billionaires and dreamy engineers.
How Virgin Galactic, regulators and the public respond to this most recent tragedy will determinewhether and how soon private space travel can transcend that playground.There is no doubt that space flight entails risks, and to pioneer a new mode of travel is to face those risks, and to reduce them.with the benefit of hard-won experience.
What is said about the failure of VSS Enterprise?

A．It may lead to the bankruptcy of Virgin Galactic.
B．It has a strong negative impact on space tourism.
C．It may discourage rich people from space travel.
D．It has aroused public attention to safety issues.
