Q: Extract the answer to the question from the following context. Question: What part keeps cells cool? Context: The epidermis is typically 10 to 30 cells thick; its main function is to provide a waterproof layer. Its outermost cells are constantly lost; its bottommost cells are constantly dividing and pushing upward. The middle layer, the dermis, is 15 to 40 times thicker than the epidermis. The dermis is made up of many components, such as bony structures and blood vessels. The hypodermis is made up of adipose tissue. Its job is to store lipids, and to provide cushioning and insulation. The thickness of this layer varies widely from species to species.
A: The hypodermis

Q: Extract the answer to the question from the following context. Question: Who was attempting a takeover of a Gaddafi ally? Context: In 1979, the U.S. placed Libya on its list of "State Sponsors of Terrorism", while at the end of the year a demonstration torched the U.S. embassy in Tripoli in solidarity with the perpetrators of the Iran hostage crisis. The following year, Libyan fighters began intercepting U.S. fighter jets flying over the Mediterranean, signalling the collapse of relations between the two countries. Libyan relations with Lebanon and Shi'ite communities across the world also deteriorated due to the August 1978 disappearance of imam Musa al-Sadr when visiting Libya; the Lebanese accused Gaddafi of having him killed or imprisoned, a charge he denied. Relations with Syria improved, as Gaddafi and Syrian President Hafez al-Assad shared an enmity with Israel and Egypt's Sadat. In 1980, they proposed a political union, with Libya paying off Syria's 1 billion debt to the Soviet Union; although pressures led Assad to pull out, they remained allies. Another key ally was Uganda, and in 1979, Gaddafi sent 2,500 troops into Uganda to defend the regime of President Idi Amin from Tanzanian invaders. The mission failed; 400 Libyans were killed and they were forced to retreat. Gaddafi later came to regret his alliance with Amin, openly criticising him.
A: Tanzanian invaders

Q: Extract the answer to the question from the following context. Question: Why we people voiding warranty of the MacIntosh? Context: Updated Motorola CPUs made a faster machine possible, and in 1987 Apple took advantage of the new Motorola technology and introduced the Macintosh II at $5500, powered by a 16 MHz Motorola 68020 processor. The primary improvement in the Macintosh II was Color QuickDraw in ROM, a color version of the graphics language which was the heart of the machine. Among the many innovations in Color QuickDraw were the ability to handle any display size, any color depth, and multiple monitors. The Macintosh II marked the start of a new direction for the Macintosh, as now for the first time it had an open architecture with several NuBus expansion slots, support for color graphics and external monitors, and a modular design similar to that of the IBM PC. It had an internal hard drive and a power supply with a fan, which was initially fairly loud. One third-party developer sold a device to regulate fan speed based on a heat sensor, but it voided the warranty. Later Macintosh computers had quieter power supplies and hard drives.
A: a fan, which was initially fairly loud

Q: Extract the answer to the question from the following context. Question: Peristalsis is a form of what? Context: Underlying the process is muscle movement throughout the system through swallowing and peristalsis. Each step in digestion requires energy, and thus imposes an "overhead charge" on the energy made available from absorbed substances. Differences in that overhead cost are important influences on lifestyle, behavior, and even physical structures. Examples may be seen in humans, who differ considerably from other hominids (lack of hair, smaller jaws and musculature, different dentition, length of intestines, cooking, etc.).
A:
muscle movement
