Article: 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).

Question: The color of the brain inside is what?
Ans: white


Article: Bell is also credited with developing one of the early versions of a metal detector in 1881. The device was quickly put together in an attempt to find the bullet in the body of U.S. President James Garfield. According to some accounts, the metal detector worked flawlessly in tests but did not find the assassin's bullet partly because the metal bed frame on which the President was lying disturbed the instrument, resulting in static. The president's surgeons, who were skeptical of the device, ignored Bell's requests to move the president to a bed not fitted with metal springs. Alternatively, although Bell had detected a slight sound on his first test, the bullet may have been lodged too deeply to be detected by the crude apparatus.

Question: What was in James Garfield that they wanted to get out?
Ans: bullet

Article: New Haven lies at the intersection of Interstate 95 on the coast—which provides access southwards and/or westwards to the western coast of Connecticut and to New York City, and eastwards to the eastern Connecticut shoreline, Rhode Island, and eastern Massachusetts—and Interstate 91, which leads northward to the interior of Massachusetts and Vermont and the Canadian border. I-95 is infamous for traffic jams increasing with proximity to New York City; on the east side of New Haven it passes over the Quinnipiac River via the Pearl Harbor Memorial, or "Q Bridge", which often presents a major bottleneck to traffic. I-91, however, is relatively less congested, except at the intersection with I-95 during peak travel times.

Question: What major interstate in New Haven provides access northward into Massachusetts, Vermont, and eventually reaches the Canadian border?
Ans:
Interstate 91
