Answer the following question given this paragraph: If an ore is deep below Earth's surface it may be too expensive to remove all the rock above it. These deposits are taken by underground mining. Underground mines can be very deep. The deepest gold mine in South Africa is more than 3,700 m deep (that is more than 2 miles)! There are various methods of underground mining. Underground mining is more expensive than surface mining. Tunnels must be blasted into the rock so that miners and equipment can get to the ore. Underground mining is dangerous work. Fresh air and lights must be brought in to the tunnels for the miners. The miners breathe in lots of particles and dust while they are underground. The ore is drilled, blasted, or cut away from the surrounding rock and taken out of the tunnels. Sometimes there are explosions as ore is being drilled or blasted. This can lead to a mine collapse. Miners may be hurt or killed in a mining accident. Q: In what type of mining must tunnels be blasted into the rock so that miners and equipment can get to the ore? Choices: - open-pit mining - strip mining - gold mining - underground mining A:
underground mining
Answer the following question given this paragraph: Some volcanic eruptions are non-explosive ( Figure below ). This happens when there is little or no gas. The lava is thin, fluid and runny. It flows over the ground like a river. People generally have a lot of warning before a lava flow like this reaches them, so non-explosive eruptions are much less deadly. They may still be destructive to property, though. Even when we know that a lava flow is approaching, there are few ways of stopping it!. Q: What kind of volcanic eruptions are less deadly? Choices: - non-dormant - serial eruptions - explosive - non-explosive A:
non-explosive
Q: Answer the following question given this paragraph: A gated channel protein is a transport protein that opens a "gate," allowing a molecule to pass through the membrane. Gated channels have a binding site that is specific for a given molecule or ion. A stimulus causes the "gate" to open or shut. The stimulus may be chemical or electrical signals, temperature, or mechanical force, depending on the type of gated channel. For example, the sodium gated channels of a nerve cell are stimulated by a chemical signal which causes them to open and allow sodium ions into the cell. Glucose molecules are too big to diffuse through the plasma membrane easily, so they are moved across the membrane through gated channels. In this way glucose diffuses very quickly across a cell membrane, which is important because many cells depend on glucose for energy. Q: What do many cells depend on glucose for? Choices: - food - heating - osmosis - energy A:
A: energy
Question: Answer the following question given this paragraph: No new mutations are occurring. Therefore, no new alleles are being created. Q: What is necessary for new alleles to be created? Choices: - cross-pollination - new rna - new frequencies - new mutations A:
Answer: new mutations

Answer the following question given this paragraph: Ground tissue makes up much of the inside of a plant. The cells of ground tissue carry out basic metabolic functions and other biochemical reactions. Ground tissue may also store food or water. Q: What type of tissue makes up much of the inside of a plant? Choices: - leaf tissue - stem tissue - working tissue - ground tissue A:
**Answer**
ground tissue
