input with options: Answer the following question given this paragraph: The acidity of a solution is typically assessed experimentally by measurement of its pH. The pOH of a solution is not usually measured, as it is easily calculated from an experimentally determined pH value. The pH of a solution can be directly measured using a pH meter (Figure 14.4). Q: The acidity of a solution is typically assessed experimentally by measurement of its what? A:
OPTIONS:
- mass
- density
- color
- ph
output: ph

Q: Answer the following question given this paragraph: Water is an example of a common chemical compound. As you can see in the Figure below , each water molecule consists of two atoms of hydrogen and one atom of oxygen. Water always has this 2:1 ratio of hydrogen to oxygen. Like water, all compounds consist of a fixed ratio of elements. It doesn't matter how much or how little of a compound there is. It always has the same composition. Q: What molecule consists of two atoms of hydrogen and one atom of oxygen? A:

OPTIONS:
- carbon monoxide
- hydrogen peroxide
- air
- water

A: water

input: OPTIONS:
- tides
- gravity
- humidity
- wind Now, answer this question: Answer the following question given this paragraph: Ocean waves are energy traveling through water. They are caused mainly by wind blowing over the water. Q: What are ocean waves mainly caused by? A:
A:
output: wind

Answer the following question given this paragraph: The most noticeable magnetic activity of the Sun is the appearance of sunspots. Sunspots are cooler, darker areas on the Sun's surface ( Figure below ). Sunspots occur in an 11 year cycle. The number of sunspots begins at a minimum. The number gradually increases to the maximum. Then the number returns to a minimum again. Q: What is the name for the cooler, darker areas on the sun's surface? A:

OPTIONS:
- corona
- aurora borealis
- anomalies
- sunspots

Answer: sunspots

Problem: OPTIONS:
- Centaurus
- Andromeda
- Bode's Galaxy
- milky way
Q: Answer the following question given this paragraph: Compared to Earth, the solar system is a big place. But galaxies are bigger - a lot bigger. A galaxy is a very large group of stars held together by gravity. How enormous a galaxy is and how many stars it contains are impossible for us to really understand. A galaxy contains up to a few billion stars! Our solar system is in the Milky Way Galaxy. It is so large that if our solar system were the size of your fist, the galaxy's disk would be wider than the entire United States! There are several different types of galaxies, and there are billions of galaxies in the universe. Q: What galaxy is our solar system a part of? A:
Answer: milky way

Answer the following question given this paragraph: Bathymetric maps are made from depth soundings or sonar data. They help oceanographers understand the shape of bottoms of lakes, bays, and the ocean. This information also helps boaters navigate safely. Q: Besides depth soundings, what else are bathymetric maps made of? A:

OPTIONS:
- intensity data
- solar data
- density measures
- sonar data

Answer:
sonar data
