Answer the following question given this paragraph: Creep usually takes place where the ground freezes and thaws frequently. Soil and rock particles are lifted up when the ground freezes. When the ground thaws, the particles settle down again. Each time they settle down, they move a tiny bit farther down the slope because of gravity. Q: Creep, which usually takes place where the ground freezes and thaws frequently, involves movement of particles due to what force? A:
OPTIONS:
- friction
- wind
- normal
- gravity
gravity

Q: Answer the following question given this paragraph: Most hormones are controlled by negative feedback in which the hormone feeds back to decrease its own production. This type of feedback brings things back to normal whenever they start to become too extreme. Positive feedback is much less common because it causes conditions to become increasingly extreme. Q: Most hormones are controlled by what type of feedback, which causes the hormone to decrease its own production? A:

OPTIONS:
- positive
- neutral
- unusual
- negative

A: negative
