input: OPTIONS:
- surface mining
- edge mining
- pit mining
- strip mining Now, answer this question: Answer the following question given this paragraph: Other methods of surface mining include strip mining, placer mining, and dredging. Strip mining is like open pit mining but with material removed along a strip. A quarry is a type of open-pit mine that produces rocks and minerals that are used to make buildings and roads. Q: What is the type of mining called when materials are removed along a strip? A:
A:
output: strip mining

Answer the following question given this paragraph: It's easy to get lost in the discussion of dinosaurs and theories about why they went extinct 65 million years ago. Was it due to a meteor slamming into Earth near the coast of modern-day Mexico, or was it from some long-term weather cycle that is not yet understood? One hypothesis that will never be proposed is that humans had something to do with it. Mammals were small, insignificant creatures of the forest 65 million years ago, and no humans existed. Woolly mammoths, however, began to go extinct about 10,000 years ago, when they shared the Earth with humans who were no different anatomically than humans today (Figure 45.12). Mammoths survived in isolated island populations as recently as 1700 BC. We know a lot about these animals from carcasses found frozen in the ice of Siberia and other regions of the north. Scientists have sequenced at least 50 percent of its genome and believe mammoths are between 98 and 99 percent identical to modern elephants. It is commonly thought that climate change and human hunting led to their extinction. A 2008 study estimated that climate change reduced the mammoth's range from 3,000,000 square miles 42,000 years [7] ago to 310,000 square miles 6,000 years ago. It is also well documented that humans hunted these animals. A 2012 study showed that no single factor was exclusively responsible for the extinction of these [8] magnificent creatures. In addition to human hunting, climate change, and reduction of habitat, these scientists demonstrated another important factor in the mammoth's extinction was the migration of humans across the Bering Strait to North America during the last ice age 20,000 years ago. The maintenance of stable populations was and is very complex, with many interacting factors determining the outcome. It is important to remember that humans are also part of nature. Once we contributed to a species' decline using primitive hunting technology only. Q: Mammoths, close genetic relatives of modern elephants, are believed to have gone extinct due to hunting by humans and what factor? A:

OPTIONS:
- volcanic eruptions
- earthquakes
- migration change
- climate change

Answer: climate change

Problem: OPTIONS:
- omnivores
- plastids
- monocots
- autotrophs
Q: Answer the following question given this paragraph: Autotrophs are organisms that make their own food. Most autotrophs use the energy in sunlight to make food in a process called photosynthesis . Only three types of organismsplants, algae, and some bacteriacan make food through photosynthesis. Examples of each type of photosynthetic organism are shown in Figure below . Q: What is the term for organisms that make their own food? A:
Answer: autotrophs

Problem:OPTIONS:
- weight and energy
- mass and potential
- heat and velocity
- energy and heat

Answer the following question given this paragraph: Joules and calories are the units of energy and heat. Q: Joules and calories are the units of what? A:
****
A: energy and heat

Answer the following question given this paragraph: A meteoroid is dragged toward Earth by gravity and enters the atmosphere. Friction with the atmosphere heats the object quickly, so it starts to vaporize. As it flies through the atmosphere, it leaves a trail of glowing gases. The object is now a meteor. Most meteors vaporize in the atmosphere. They never reach Earth's surface. Large meteoroids may not burn up entirely in the atmosphere. A small core may remain and hit Earth's surface. This is called a meteorite . Q: What causes a meteoroid to vaporize after it enters the atmosphere? A:
OPTIONS:
- gravitational pull
- atmospheric pressure
- spontaneous combustion
- friction with atmosphere
friction with atmosphere

Answer the following question given this paragraph: An ionic bond is the force of attraction that holds together positive and negative ions. It forms when atoms of a metallic element give up electrons to atoms of a nonmetallic element. Q: What is the the force of attraction that holds together ions? A:
OPTIONS:
- covalent bond
- soluble bond
- magnetic bond
- ionic bond

Answer:
ionic bond
