Background: Acceleration is a measure of the change in velocity of a moving object. It measures the rate at which velocity changes. Velocity, in turn, is a measure of the speed and direction of motion, so a change in velocity may reflect a change in speed, a change in direction, or both. Both velocity and acceleration are vectors. A vector is any measurement that has both size and direction. People commonly think of acceleration as in increase in speed, but a decrease in speed is also acceleration. In this case, acceleration is negative and called deceleration. A change in direction without a change in speed is acceleration as well. Paragraph: Angela is driving on a highway. She is stuck between two cars but needs to get to the off ramp and decides to speed up. She hits the gas making her car go faster so she can get ahead of the two cars she is stuck in between and makes it to the ramp in time. Given the paragraph above, please answer correctly the following question: Which thing did Angela's car do, accelerate or decelerate?
----
Answer: accelerate

Background: Unfortunately, the layer of good ozone is being destroyed by air pollution. The chief culprits are chlorine and bromine gases. They are released in aerosol sprays, coolants, and other products. Loss of ozone has created an ozone hole over Antarctica. Ozone depletion results in higher levels of UV radiation reaching Earth. In humans, this increases skin cancers and eye cataracts. It also disturbs the nitrogen cycle, kills plankton, and disrupts ocean food webs. The total loss of the ozone layer would be devastating to most life. It's rate of loss has slowed with restrictions on pollutants, but it is still at risk. Paragraph: The researches studied the atmosphere in Antarctica, and close to Greenland. They found out there's an ozone hole over Antarctica. Given the paragraph above, please answer correctly the following question: Which landmass had lower levels of UV radiation reaching it?
----
Answer: Greenland

Background: When you go to the dentist to get a tooth pulled, you really don't want to feel any pain. The dentist injects an anesthetic into your gum and it eventually becomes numb. One theory as to why anesthetics work deals with the movement of ions across the cell membrane. The anesthetic gets into the membrane structure and causes shifts in how ions move across the membrane. If ion movement is disrupted, nerve impulses will not be transmitted and you will not sense pain at least not until the anesthetic wears off. Paragraph: Two men in the Vietnam War needed to have their arms amputated. Unfortunately, the men were not able to be knocked unconscious for the operation. The doctor asked each patient if they wanted anesthetic injected into their arm or not. Marco replied that he wanted some, and Luke declined any anesthetic. Given the paragraph above, please answer correctly the following question: Which person's ions will be able to move across the cell membrane?
----
Answer:
Luke
