[EX Q]: The dermis is the inner layer of skin. The dermis has blood vessels and nerve endings. The nerve endings explain why your skin is sensitive. You can sense pain, pressure, and temperature. You cut your finger and it starts to bleed. What has happened? If your skin bleeds, it means you have cut the dermis layer and damaged blood vessels. The cut really hurts. It hurts because of the nerve endings in this skin layer. The dermis also contains hair follicles and two types of glands. Hair follicles are structures where hairs originate. Each hair grows out of a follicle. Hair passes up through the epidermis. It then extends above the skin surface. Oil glands produce an oily substance. The oil is secreted into hair follicles. <sep>Why is the dermis a very important part of your skin makeup?<sep>It is important because it allows you to feel conditions with your skin
[EX A]: Yes

[EX Q]: The world can be divided into three climate zones. The first climate zone is the polar zone. As it sounds, the polar zone is near earths poles. The polar zone has very long and cold winters. Brrr!!!! Near the equator is the tropical zone. The tropical zone is known for being hot and wet. Between these two zones is the temperate zone. Temperatures there tend to be mild. Its not too hot and not too cold. You might expect places near the equator to be hot and wet. Thats not always the case. Sometimes there are other factors at work. These factors can affect the local climate type or a region. Oceans and mountain ranges can have a major impact. They can greatly influence the climate of an area. Many factors influence an areas climate. <sep>In which zone are temperatures neither too hot nor too cold?<sep>Central
[EX A]: No

[EX Q]: Alien Planet starts out with an interstellar spacecraft named Von Braun , leaving Earth's orbit .  Traveling at 20 % the speed of light , it reaches Darwin IV in 42 years .  Upon reaching orbit , it deploys the Darwin Reconnaissance Orbiter , Which looks for potential landing sites for the probes .  The first probe , Balboa , explodes along with its lifting body transport during entry , because one of its wings failed to unfold .  Two backup probes , Leonardo da Vinci and Isaac Newton , successfully land on the planet , and learn much about its bizarre indigenous lifeforms , including an apparently sapient species .  The robotic probes sent out to research on Darwin IV are called Horus Probes .  Each Horus probe consists of an { { convert } } long inflatable , hydrogen-filled balloon , Which is covered with solar receptors , a computer ` brain ' , a ` head ' covered with sensors , and several smaller robots that can be sent to places too dangerous for the probes themselves .  The probes have a limited degree of artificial intelligence , very similar to the ` processing power ' of a 4-year-old .  All the real thinking is done by a supercomputer in the orbiting Von Braun .  The probes are programmed with different personalities ; Ike is more cautious , while Leo is the risk-taker .  The two probes are also equipped with a holographic message that will be projected to any sentient life found on Darwin .  After the two probes inflate their gas-bags , they encounter a voracious Arrowtongue and watch it pursue a Gyrosprinter . <sep>Which interstellar spacecraft is used by Alien Planet to reach Darwin IV?<sep>Leonardo da Vinci
[EX A]:
No
