Answer the following question given this paragraph: An underground layer of rock that is saturated with groundwater is called an aquifer . A diagram of an aquifer is shown in Figure below . Aquifers are generally found in porous rock, such as sandstone. Water infiltrates the aquifer from the surface. The water that enters the aquifer is called recharge. Q: What is the term for an underground layer of rock that is saturated with groundwater? A:
OPTIONS:
- delta
- river
- bason
- aquifer

Answer: aquifer

Question: Answer the following question given this paragraph: Unlike protons and neutrons, which are located inside the nucleus at the center of the atom, electrons are found outside the nucleus. Because opposite electric charges attract each other, negative electrons are attracted to the positive nucleus. This force of attraction keeps electrons constantly moving through the otherwise empty space around the nucleus. The Figure below is a common way to represent the structure of an atom. It shows the electron as a particle orbiting the nucleus, similar to the way that planets orbit the sun. Q: Where are protons and neutrons located? A:
OPTIONS:
- radius
- electron shell
- epidermis
- nucleus
Answer: nucleus

input with options: Answer the following question given this paragraph: Q: Our global ecological footprint depends on resource use per person and what population factor? A:
OPTIONS:
- population fluctuation
- population sample
- population decrease
- population density
output: population density

Q: Answer the following question given this paragraph: The epidermis is the outer layer of skin, consisting of epithelial cells and little else (see Figure below ). For example, there are no nerve endings or blood vessels in the epidermis. The innermost cells of the epidermis are continuously dividing through mitosis to form new cells. The newly formed cells move up through the epidermis toward the skin surface, while producing a tough, fibrous protein called keratin . The cells become filled with keratin and die by the time they reach the surface, where they form a protective, waterproof layer called the stratum corneum . The dead cells are gradually shed from the surface of the skin and replaced by other cells. Q: What is the name of the outer layer of skin? A:

OPTIONS:
- endodermis
- hypodermis
- the dermis
- the epidermis

A: the epidermis

Answer the following question given this paragraph: Extrusive igneous rocks form above the surface. The lava cools quickly as it pours out onto the surface ( Figure below ). Extrusive igneous rocks cool much more rapidly than intrusive rocks. The rapid cooling time does not allow time for large crystals to form. So igneous extrusive rocks have smaller crystals than igneous intrusive rocks. Extrusive igneous rocks are also called volcanic rocks . Q: Extrusive igneous rocks are also called what? A:
OPTIONS:
- metamorphic
- agates
- magma minerals
- volcanic rocks
volcanic rocks
