Answer the following question given this paragraph: There is a lot of volcanic activity at divergent plate boundaries in the oceans. As the plates pull away from each other, they create deep fissures. Molten lava erupts through these cracks. The East Pacific Rise is a divergent plate boundary in the Pacific Ocean ( Figure below ). The Mid-Atlantic Ridge is a divergent plate boundary in the Atlantic Ocean. Q: In what ocean is the mid-atlantic ridge located? Choices: - indian ocean - pacific ocean - arctic ocean - atlantic ocean A:
atlantic ocean

Question: Answer the following question given this paragraph: A small child darts in front of your bike as you race down the street. You see the child and immediately react. You put on the brakes, steer away from the child, and yell out a warning, all in just a split second. How do you respond so quickly? Such rapid responses are controlled by your nervous system. The nervous system is a complex network of nervous tissue that carries electrical messages throughout the body. It includes the brain and spinal cord, the central nervous system , and nerves that run throughout the body, the peripheral nervous system (see Figure below ). To understand how nervous messages can travel so quickly, you need to know more about nerve cells. Q: What is the complex network of nervous tissue that carries electrical messages throughout the body? Choices: - respiratory system - circulatory system - lymphatic system - nervous system A:
Answer: nervous system

Answer the following question given this paragraph: Hydrogen has the smallest, lightest atoms of all elements. Pure hydrogen is a colorless, odorless, tasteless gas that is nontoxic but highly flammable. Hydrogen gas exists mainly as diatomic ("two-atom") molecules (H 2 ), as shown in the diagram on the right. Hydrogen is the most abundant element in the universe and the third most abundant element on Earth, occurring mainly in compounds such as water. Q: What has the smallest, lightest atoms of all the elements and is colorless, odorless, tasteless and nontoxic, but highly flammable in its pure state? Choices: - helium - magnesium - barium - hydrogen A:
**Answer**
hydrogen
