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 summer. As it worked through a wider postmortem (事后剖析) of the financial meltdown, the group of MPs sought to address the widely asked question of whether more women at the top would have prevented the crisis. The group of MPs sought to find the answer for the question______.
A．that city diversity is an ever-lasting career B．whether more women of senior positions can prevent crisis C．that more women at the top can do good for economic crisis D．whether more women can be hired to solve economic crisis
