Answer the following question given this paragraph: Shock Hazards Electrical currents through people produce tremendously varied effects. An electrical current can be used to block back pain. The possibility of using electrical current to stimulate muscle action in paralyzed limbs, perhaps allowing paraplegics to walk, is under study. TV dramatizations in which electrical shocks are used to bring a heart attack victim out of ventricular fibrillation (a massively irregular, often fatal, beating of the heart) are more than common. Yet most electrical shock fatalities occur because a current put the heart into fibrillation. A pacemaker uses electrical shocks to stimulate the heart to beat properly. Some fatal shocks do not produce burns, but warts can be safely burned off with electric current (though freezing using liquid nitrogen is now more common). Of course, there are consistent explanations for these disparate effects. The major factors upon which the effects of electrical shock depend are 1. The amount of current. Q: A pacemaker uses electrical shocks to stimulate the what to beat properly? A:

OPTIONS:
- brain
- pancreas
- liver
- heart

Answer: heart

Problem: OPTIONS:
- purple, blue
- blue, green
- yellow, white
- red, orange
Q: Answer the following question given this paragraph: "Neon" signs are familiar examples of gas discharge tubes. However, only signs that glow with the red-orange color seen in the figure are actually filled with neon. Signs of other colors contain different gases or mixtures of gases. Q: What colors in a neon sign represent real neon? A:
Answer: red, orange

Problem:OPTIONS:
- weight
- light
- traction
- gravity

Answer the following question given this paragraph: Like water in the ocean, air in the atmosphere exerts pressure that increases with depth. Most gas molecules in the atmosphere are pulled close to Earth's surface by gravity. As a result, air pressure decreases quickly at lower altitudes and then more slowly at higher altitudes. This is illustrated in Figure below . Air pressure is greatest at sea level, where the depth of the atmosphere is greatest. At higher altitudes, the pressure is less because the depth of the atmosphere is less. For example, on top of Mount Everest, the tallest mountain on Earth, air pressure is only about one-third of the pressure at sea level. At such high altitudes, low air pressure makes it hard to breathe and is dangerous to human health. Q: Most gas molecules in the atmosphere are pulled close to earth's surface by what force? A:
****
A: gravity

Answer the following question given this paragraph: Scientists often study the effects of environment on phenotype by studying identical twins. Identical twins have the same genes, so phenotypic differences between twins often have an environmental cause. Twin studies help understand the relative importance of environmental and genetic influences on individual traits and behaviors. Twins are a valuable source of information concerning the relationship between genes and environment. As monozygotic twins (identical) share their nuclear DNA, their polymorphisms , the nucleotide differences that make their DNA unique, are common to the two individuals. This means that any phenotypic variation, such as in height, intelligence, or any other measurable trait, is due to the environment. What is different about the experiences of the twins? What unique experiences might one twin have that the other twin did not have? By comparing phenotypes of hundreds of twins, researchers can understand the roles of genetics, shared environment and unique experiences in the formation and development of specific traits. Q: What is often the cause of phenotypic differences between identical twins? A:
OPTIONS:
- natural selection
- genetics
- learned behavior
- environment

Answer the following question given this paragraph: A: If calcium chloride dissolves in water, it breaks down into its ions (Ca 2+ and Cl - ). When water has ions dissolved in it, it has a lower freezing point. Pure water freezes at 0C. With calcium and chloride ions dissolved in it, it won't freeze unless the temperature reaches -29C or lower. Q: In celsius, what is the temperature at which water freezes? A:
OPTIONS:
- 32 degrees
- 100 degrees
- absolute zero
- zero degrees

Answer: zero degrees

input with options: Answer the following question given this paragraph: You must have a GPS receiver to use the system. You can buy many types of these in stores. The GPS receiver detects radio signals from nearby GPS satellites. There are precise clocks on each satellite and in the receiver. The receiver measures the time for radio signals from satellites to reach it. The receiver uses the time and the speed of radio signals to calculate the distance between the receiver and the satellite. The receiver does this with at least four different satellites to locate its position on the Earth's surface ( Figure above ). GPS receivers are now being built into many items, such as cell phones and cars. Q: What do we call the worldwide radio-navigation system formed from a constellation of 24 satellites and their ground stations? A:
OPTIONS:
- cellular network
- radio waves
- compass
- gps
output:
gps
