Q: Answer the following question given this paragraph:   Atherosclerosis is a condition in which a material called plaque builds up inside arteries. Plaque consists of cell debris, cholesterol, and other substances. As plaque builds up in an artery, the artery narrows, as shown in Figure below . This reduces blood flow through the artery.   Q: What is a condition in which a material called plaque builds up inside arteries?   A:
Answer: atherosclerosis

Problem:OPTIONS:
- ozone depletion

Elastic force is the counter force that resists the stretching or compressing of an elastic material.   Q: What is the ability of a material to return to its original shape after being stretched or compressed?   A:
OPTIONS:

elasticity

Answer the following question given this paragraph:   For example, in the fall, when the days start to get shorter, the trees sense that there is less sunlight. The plant is stimulated, and it sends messages telling the leaves to change colors and fall. This is an example of photoperiodism , the reaction of organisms, such as plants, to the length of day or night. Photoperiodism is also the reaction of plants to the length of light and dark periods. Many flowering plants sense the length of night, a dark period, as a signal to flower. Each plant has a different photoperiod, or night length. When the plant senses the appropriate length of darkness, resulting in an appropriate length of daylight, it flowers. Flowering plants are classified as long-day plants or short-day plants. Long-day plants flower when the length of daylight exceeds the necessary photoperiod, and short-day plants flower when the day length is shorter than the necessary photoperiod. Long-day plants include carnations, clover, lettuce, wheat, and turnips. Short-day plants include cotton, rice, and sugar cane.   Q: What happens to the length of the days in the fall?   A:
OPTIONS:
- they stay the same
- they change randomly
- they get longer
- they get shorter

Answer: they get shorter
