{{B}}One Good Reason to Let Smallpox Live{{/B}}

If smallpox had truly gone from the planet, what point was there in keeping these reserves

(46) Within a few years, the mobile phone will evolve from a voice-only device to a multi-functional communicator capable of transmitting and receiving not only sound, but video, still images, data and text. A whole new era of personal communication is on the way.
Thanks in part to the growth of wireless networks, the telephone is converging with the personal computer and the television. (47) Soon light-weight phones outfitted with high resolution screens--which can be embedded in everything from wristwatches to palm-held units will be connected to series of low orbit satellites enabling people to talk, send and receive E-mail, or take part in video conferences anytime, anywhere.

[单项选择]The banking industry urgently needs to hire more women in senior jobs if it is to banish(驱除) the dangerous culture of "groupthink" that contributed to the financial crisis, a report by a cross-party group of MPs recommends.
While more women in the city would not have prevented the global meltdown (崩溃) in the financial system, more diversity may have helped senior figures question each other rather than all too often adopting a group of people’s mentality, according to the Treasury select committee.
The 14-member committee--whose only woman is Northampton MP Sally Keeble--stopped short of calling for quotas on female board representation in financial firms or for legal changes to boost the image of women in the city. But it did criticize the financial sector’s slowness in combating a family-unfriendly long-hours culture and highlighted a gender pay gap that is even wider than for the economy as a whole.
The committee launched its investigation into city diversity last sum
A. prevent the global meltdown in the financial system
B. help senior figures to have different opinions
C. help senior figures to adopt the same ideas
D. help men to work more efficiently
