Answer the following question given this paragraph: Plants don't have an immune system, but they do respond to disease. Typically, their first line of defense is the death of cells surrounding infected tissue. This prevents the infection from spreading. Q: Because plants lack what kind of system, their first line of defense is usually the death of cells surrounding infected tissue to prevent spread of infection? A:

OPTIONS:
- nervous system
- digestion system
- hormones system
- immune system

Answer: immune system

Problem: OPTIONS:
- trees
- grasses
- weeds
- ferns
Q: Answer the following question given this paragraph: Ferns are the most common seedless vascular plants ( Figure below ). They usually have large divided leaves called fronds. In most ferns, fronds develop from a curled-up formation called a fiddlehead ( Figure below ). The fiddlehead looks like the curled decoration on the end of a stringed instrument, such as a fiddle. Leaves unroll as the fiddleheads grow and expand. Ferns grow in a variety of habitats, ranging in size from tiny aquatic species to giant tropical plants. Q: What are the most common seedless vascular plants? A:
Answer: ferns

Problem:OPTIONS:
- philosophic method
- rhythm method
- Socratic method
- scientific method

Answer the following question given this paragraph: Sometime in your life you've asked a question about the world around you. Probably you've asked a lot of questions over the years. The best way to answer questions about the natural world is by using science. Scientists ask questions every day, and then use a set of steps to answer those questions. The steps are known as the scientific method. By following the scientific method, scientists come up with the best information about the natural world. As a scientist, you need to do experiments to find out about the world. You also need to wonder, observe, talk, and think. Everything we learn helps us to ask new and better questions. Q: What is the set of steps that scientists use to learn about the world? A:
****
A: scientific method

Answer the following question given this paragraph: There are very few living species of monotremes, or egg-laying mammals. They include the echidna and platypus, both pictured in Figure below . Monotremes are found only in Australia and the nearby island of New Guinea. Q: What's another term for egg-laying mammals? A:
OPTIONS:
- viviparus
- amphibians
- herbivores
- monotremes
monotremes

Answer the following question given this paragraph: Parasitic roundworms may have plant, vertebrate, or invertebrate hosts. Several species have human hosts. For example, hookworms, like the one in Figure below , are human parasites. They infect the human intestine. They are named for the hooks they use to grab onto the host's tissues. Hookworm larvae enter the host through the skin. They migrate to the intestine, where they mature into adults. Adults lay eggs, which pass out of the host in feces. Then the cycle repeats. Q: Through which organ do hookworm larvae enter the human body? A:
OPTIONS:
- through the lungs
- through the rectum
- through the mouth
- through the skin

Answer: through the skin

input with options: Answer the following question given this paragraph: One dimensional motion describes objects moving in straight lines. Speed is a scalar measure of how quickly an object is moving along this line. Velocity is speed with a direction, making it a vector. If an object's velocity changes with time, the object is said to be accelerating. When restricted to one dimension, there are only two possible directions for the velocity and acceleration vectors to point in. As we'll see in the next chapters, understanding an object's acceleration is the key to understanding its motion. Q: What is the term for a scalar measure of how quickly an object is moving along this line? A:
OPTIONS:
- velocity
- motion
- force
- speed
output:
speed
