Question: Answer the following question given this paragraph: The only completely effective way to prevent infection with STIs is to avoid sexual contact and other risky behaviors. Using condoms can lower the risk of becoming infected with STIs during some types of sexual activity. However, condoms are not foolproof. Pathogens may be present on areas of the body not covered by condoms. Condoms can also break or be used incorrectly. Q: What is the only way to completely avoid stis? A:
OPTIONS:
- cover your mouth
- oral sex
- contraceptive use
- avoid sexual contact
Answer: avoid sexual contact

input with options: Answer the following question given this paragraph: low, the two metals with the highest ionization energies (beryllium and magnesium) do form compounds that exhibit some covalent characters. Like the alkali metals, the heavier alkaline earth metals impart color to a flame. As in the case of the alkali metals, this is part of the emission spectrum of these elements. Calcium and strontium produce shades of red, whereas barium produces a green color. Magnesium is a silver-white metal that is malleable and ductile at high temperatures. Passivation decreases the reactivity of magnesium metal. Upon exposure to air, a tightly adhering layer of magnesium oxycarbonate forms on the surface of the metal and inhibits further reaction. (The carbonate comes from the reaction of carbon dioxide in the atmosphere. ) Magnesium is the lightest of the widely used structural metals, which is why most magnesium production is for lightweight alloys. Magnesium (shown in Figure 18.6), calcium, strontium, and barium react with water and air. At room temperature, barium shows the most vigorous reaction. The products of the reaction with water are hydrogen and the metal hydroxide. The formation of hydrogen gas indicates that the heavier alkaline earth metals are better reducing agents (more easily oxidized) than is hydrogen. As expected, these metals react with both acids and nonmetals to form ionic compounds. Unlike most salts of the alkali metals, many of the common salts of the alkaline earth metals are insoluble in water because of the high lattice energies of these compounds, containing a divalent metal ion. Q: Which is the lightest of the widely used structural metals? A:
OPTIONS:
- Metal
- calcium
- potassium
- magnesium
output: magnesium

Q: Answer the following question given this paragraph: DNA's three-dimensional structure is a double helix. The hydrogen bonds between the bases at the center of the helix hold the helix together. Q: What type of bonds between the bases at the center of the dna double helix hold the helix together? A:

OPTIONS:
- helium bonds
- ionic bonds
- electron bonds
- hydrogen bonds

A: hydrogen bonds

input: OPTIONS:
- neither
- mixed
- small
- large Now, answer this question: Answer the following question given this paragraph: Q: Do motile cilia usually occur in small or large numbers on the cell surface? A:
A:
output: large

Answer the following question given this paragraph: Burning of fossil fuels, such as oil, releases carbon into the atmosphere. This carbon must be cycled - removed from the atmosphere - back into living organisms, or it stays in the atmosphere. Increased carbon in the atmosphere contributes to the greenhouse effect on Earth. Q: The greenhouse effect on earth is caused by an increase in what in the atmosphere? A:

OPTIONS:
- phosphorous
- vapor
- satellites
- carbon

Answer: carbon

Q: Answer the following question given this paragraph: Crocodilia Reptiles in the Crocodilia Order are called crocodilians. They include crocodiles, alligators, caimans, and gharils. They have four sprawling legs that allow them to run surprisingly fast. They have strong jaws and replace their teeth throughout life. Crocodilians have relatively complex brains and greater intelligence than other reptiles. crocodile. Q: The crocodilia order, which includes crocodiles, alligators, caimans, and gharils, is part of what class of animals? A:

OPTIONS:
- aquatic
- mammals
- parasites
- reptiles

A:
reptiles
