Problem: Houston:

Houston is recognized worldwide for its energy industry—particularly for oil and natural gas—as well as for biomedical research and aeronautics. Renewable energy sources—wind and solar—are also growing economic bases in the city. The Houston Ship Channel is also a large part of Houston's economic base. Because of these strengths, Houston is designated as a global city by the Globalization and World Cities Study Group and Network and global management consulting firm A.T. Kearney. The Houston area is the top U.S. market for exports, surpassing New York City in 2013, according to data released by the U.S. Department of Commerce's International Trade Administration. In 2012, the Houston–The Woodlands–Sugar Land area recorded $110.3 billion in merchandise exports. Petroleum products, chemicals, and oil and gas extraction equipment accounted for approximately two-thirds of the metropolitan area's exports last year. The Top 3 destinations for exports were Mexico, Canada, and Brazil.

Besides oil and gas, what is Houston known for?
---
A: biomedical research and aeronautics


Problem: Imperial College London:

In 2003, it was reported that one third of female academics "believe that discrimination or bullying by managers has held back their careers". It was said then that "A spokesman for Imperial said the college was acting on the recommendations and had already made changes". Nevertheless, allegations of bullying have continued: in 2007, concerns were raised about the methods that were being used to fire people in the Faculty of Medicine. New President of Imperial College, Alice Gast says she sees bright lights in the horizon for female careers at Imperial College London.

What portion of females reported that they were held back by managers?
---
A: one third


Problem: Printed circuit board:

Initially PCBs were designed manually by creating a photomask on a clear mylar sheet, usually at two or four times the true size. Starting from the schematic diagram the component pin pads were laid out on the mylar and then traces were routed to connect the pads. Rub-on dry transfers of common component footprints increased efficiency. Traces were made with self-adhesive tape. Pre-printed non-reproducing grids on the mylar assisted in layout. To fabricate the board, the finished photomask was photolithographically reproduced onto a photoresist coating on the blank copper-clad boards.

Self-adhesive mylar was used to make what?
---
A: unanswerable


Problem: Jews:

The studies also show that the Sephardic Bnei Anusim (descendants of the "anusim" forced converts to Catholicism) of Iberia (estimated at about 19.8% of modern Iberia) and Ibero-America (estimated at least 10% of modern Ibero-America) have Sephardic Jewish origins within the last few centuries, while the Bene Israel and Cochin Jews of India, Beta Israel of Ethiopia, and a portion of the Lemba people of Southern Africa, despite more closely resembling the local populations of their native countries, also have some more remote ancient Jewish descent.

What population does not have some more remote ancient Jewish descent?
---
A:
unanswerable
