input with options: Answer the following question given this paragraph: Irrigation is the single biggest use of water. Overhead irrigation wastes a lot of water. Drip irrigation wastes a lot less. Figure below shows a drip irrigation system. Water pipes run over the surface of the ground. Tiny holes in the pipes are placed close to each plant. Water slowly drips out of the holes and soaks into the soil around the plants. Very little of the water evaporates or runs off the ground. Q: Does overhead irrigation or drip irrigation use less water? A:
OPTIONS:
- mist irrigation
- stream irrigation
- constant flow
- drip irrigation
output: drip irrigation

input with options: Answer the following question given this paragraph: Rickets is softening of the bones in children that occurs because bones do not have enough calcium. Rickets can lead to fractures and bowing of the leg bones, which is illustrated in the Figure below . Q: Lack of what mineral causes rickets? A:
OPTIONS:
- zinc
- potassium
- magnesium
- calcium
output: calcium

input with options: Answer the following question given this paragraph: Mapping is an important part of Earth Science. Topographic maps use a line, called a contour line, to show different elevations on a map. Contour lines show the location of hills, mountains and valleys. A regular road map shows where a road goes. But a road map doesn't show if the road goes over a mountain pass or through a valley. A topographic map shows you the features the road is going through or past. Let's look at topographic maps. Q: What is the name of the line used in topographic maps that shows different elevations? A:
OPTIONS:
- a patch line
- a crater line
- a curve line
- a contour line
output: a contour line

input with options: Answer the following question given this paragraph: Comparative embryology is the study of the similarities and differences in the embryos of different species. Similarities in embryos are evidence of common ancestry. All vertebrate embryos, for example, have gill slits and tails. Most vertebrates, except for fish, lose their gill slits by adulthood. Some of them also lose their tail. In humans, the tail is reduced to the tail bone. Thus, similarities organisms share as embryos may be gone by adulthood. This is why it is valuable to compare organisms in the embryonic stage. See http://www. pbs. org/wgbh/evolution/library/04/2/pdf/l_042_03. pdf for additional information and a comparative diagram of human, monkey, pig, chicken and salamander embryos. Q: What is the study of the similarities and differences in the embryos of different species? A:
OPTIONS:
- example embryology
- prenatal biology
- diversified embryology
- comparative embryology
output:
comparative embryology
