Problem: Brain:

The brains of vertebrates are made of very soft tissue. Living brain tissue is pinkish on the outside and mostly white on the inside, with subtle variations in color. Vertebrate brains are surrounded by a system of connective tissue membranes called meninges that separate the skull from the brain. Blood vessels enter the central nervous system through holes in the meningeal layers. The cells in the blood vessel walls are joined tightly to one another, forming the blood–brain barrier, which blocks the passage of many toxins and pathogens (though at the same time blocking antibodies and some drugs, thereby presenting special challenges in treatment of diseases of the brain).

Meninges separate what structure from the brain?
---
A: the skull


Problem: Bermuda:

The island was administered as an extension of Virginia by the Company until 1614. Its spin-off, the Somers Isles Company, took over in 1615 and managed the colony until 1684. At that time, the company's charter was revoked, and the English Crown took over administration. The islands became a British colony following the 1707 unification of the parliaments of Scotland and England, which created the Kingdom of Great Britain. After 1949, when Newfoundland became part of Canada, Bermuda was automatically ranked as the oldest remaining British Overseas Territory. Since the return of Hong Kong to China in 1997, it is the most populous Territory. Its first capital, St. George's, was established in 1612 and is the oldest continuously inhabited English town in the New World.

When was China returned to Hong Kong?

A: unanswerable


Problem: New York City:

New York City is the most-populous city in the United States, with an estimated record high of 8,491,079 residents as of 2014, incorporating more immigration into the city than outmigration since the 2010 United States Census. More than twice as many people live in New York City as in the second-most populous U.S. city (Los Angeles), and within a smaller area. New York City gained more residents between April 2010 and July 2014 (316,000) than any other U.S. city. New York City's population amounts to about 40% of New York State's population and a similar percentage of the New York metropolitan area population.

About what percentage is New York City's population of the New York metropolitan area's population?
---
A: 40%


Problem: Clothing:

Though mechanization transformed most aspects of human industry by the mid-20th century, garment workers have continued to labor under challenging conditions that demand repetitive manual labor. Mass-produced clothing is often made in what are considered by some to be sweatshops, typified by long work hours, lack of benefits, and lack of worker representation. While most examples of such conditions are found in developing countries, clothes made in industrialized nations may also be manufactured similarly, often staffed by undocumented immigrants.[citation needed]

What type of clothing is frequently the product of sweatshops?
---
A:
Mass-produced
