Problem: Anti-aircraft warfare:

AAA battalions were also used to help suppress ground targets. Their larger 90 mm M3 gun would prove, as did the eighty-eight, to make an excellent anti-tank gun as well, and was widely used late in the war in this role. Also available to the Americans at the start of the war was the 120 mm M1 gun stratosphere gun, which was the most powerful AA gun with an impressive 60,000 ft (18 km) altitude capability. No 120 M1 was ever fired at an enemy aircraft. The 90 mm and 120 mm guns would continue to be used into the 1950s.

Along with the 88, what other AAA battalion gun made a good anti-tank weapon?
---
A: 90 mm M3 gun


Problem: War on Terror:

On 12 January 2002, Musharraf gave a speech against Islamic extremism. He unequivocally condemned all acts of terrorism and pledged to combat Islamic extremism and lawlessness within Pakistan itself. He stated that his government was committed to rooting out extremism and made it clear that the banned militant organizations would not be allowed to resurface under any new name. He said, "the recent decision to ban extremist groups promoting militancy was taken in the national interest after thorough consultations. It was not taken under any foreign influence".

What did Musharraf ban?
---
A: militant organizations


Problem: Database:

For instance, a common use of a database system is to track information about users, their name, login information, various addresses and phone numbers. In the navigational approach all of this data would be placed in a single record, and unused items would simply not be placed in the database. In the relational approach, the data would be normalized into a user table, an address table and a phone number table (for instance). Records would be created in these optional tables only if the address or phone numbers were actually provided.

What happens to full data fields in a navigational system?
---
A: unanswerable


Problem: Ashkenazi Jews:

The genome-wide genetic study carried out in 2010 by Behar et al. examined the genetic relationships among all major Jewish groups, including Ashkenazim, as well as the genetic relationship between these Jewish groups and non-Jewish ethnic populations. The study found that contemporary Jews (excluding Indian and Ethiopian Jews) have a close genetic relationship with people from the Levant. The authors explained that "the most parsimonious explanation for these observations is a common genetic origin, which is consistent with an historical formulation of the Jewish people as descending from ancient Hebrew and Israelite residents of the Levant".

The genome-wide genetic study carried out in 2010 by Behar et al. examined the genetic relationship between Jewish groups and what other population?
---
A:
non-Jewish ethnic populations
