Answer the following question given this paragraph: Average speed is calculated by dividing the total distance travelled by the time interval. For example, someone who takes 40 minutes to drive 20 miles north and then 20 miles south (to end up at the same place), has an average speed of 40 miles divided by 40 minutes, or 1 mile per minute (60 mph). Average velocity, however, involves total displacement, instead of distance. It is calculated by dividing the total displacement by the time interval. In this example, the driver's displacement is zero, which makes the average velocity zero mph. Q: Distance traveled divided by time is equal to what? A:

OPTIONS:
- direction
- momentum
- frequency
- speed

Answer: speed

Problem: OPTIONS:
- increase
- stay the same
- it is unable to be measured
- decrease
Q: Answer the following question given this paragraph: This is how ice wedging works. When liquid water changes into solid ice, it increases in volume. You see this when you fill an ice cube tray with water and put it in the freezer. The ice cubes go to a higher level in the tray than the water. You also may have seen this if you put a can of soda into the freezer so that it cools down quickly. If you leave the can in the freezer too long, the liquid expands so much that it bends or pops the can. (For the record, water is very unusual. Most substances get smaller when they change from a liquid to a solid. ). Q: Do most substances increase or decrease in size when they change from a liquid to a solid? A:
Answer: decrease

Answer the following question given this paragraph: From the eighth week following fertilization until birth, the developing human being is called a fetus. Birth typically occurs at about 38 weeks after fertilization, so the fetal period generally lasts about 30 weeks. During this time, the organs complete their development. The fetus also grows rapidly in length and weight. Some of the specific changes that occur during the fetal stage are listed in Figure below . Q: Approximately how many weeks does the fetal period last? A:
OPTIONS:
- 10 weeks
- 25 weeks
- 27 weeks
- 30 weeks

Answer: 30 weeks
