Answer the following question given this paragraph: Has this ever happened to you? A student sitting next to you in class has a cold. The other student is coughing and sneezing, but you feel fine. Two days later, you come down with a cold, too. Diseases like colds are contagious. Contagious diseases are also called infectious diseases. An infectious disease is a disease that spreads from person to person. Q: Meaning a disease that spreads from person to person, what term is synonymous with "contagious"? A:
OPTIONS:
- benign
- harmless
- noncommunicable
- infectious

Answer: infectious

Question: Answer the following question given this paragraph: Waves may reflect off an obstacle that they are unable to pass through. When waves are reflected straight back from an obstacle, the reflected waves interfere with the original waves and create standing waves . These are waves that appear to be standing still. Standing waves occur because of a combination of constructive and destructive interference. You can see animations of standing waves at the URLs below. Q: What do waves do when they are unable to pass through an object? A:
OPTIONS:
- produce off
- Roll over.
- develop off
- reflect off
Answer: reflect off

input with options: Answer the following question given this paragraph: 9.3 Response to the Signal The initiation of a signaling pathway is a response to external stimuli. This response can take many different forms, including protein synthesis, a change in the cell's metabolism, cell growth, or even cell death. Many pathways influence the cell by initiating gene expression, and the methods utilized are quite numerous. Some pathways activate enzymes that interact with DNA transcription factors. Others modify proteins and induce them to change their location in the cell. Depending on the status of the organism, cells can respond by storing energy as glycogen or fat, or making it available in the form of glucose. A signal transduction pathway allows muscle cells to respond to immediate requirements for energy in the form of glucose. Cell growth is almost always stimulated by external signals called growth factors. Uncontrolled cell growth leads to cancer, and mutations in the genes encoding protein components of signaling pathways are often found in tumor cells. Programmed cell death, or apoptosis, is important for removing damaged or unnecessary cells. The use of cellular signaling to organize the dismantling of a cell ensures that harmful molecules from the cytoplasm are not released into the spaces between cells, as they are in uncontrolled death, necrosis. Apoptosis also ensures the efficient recycling of the components of the dead cell. Termination of the cellular signaling cascade is very important so that the response to a signal is appropriate in both timing and intensity. Degradation of signaling molecules and dephosphorylation of phosphorylated intermediates of the pathway by phosphatases are two ways to terminate signals within the cell. Q: Programmed cell death, which goes by what term, is important for removing damaged or unnecessary cells? A:
OPTIONS:
- mytosis
- synthesis
- mutations
- apoptosis
output: apoptosis

Problem: OPTIONS:
- middle of transcription
- aftermath of transcription
- end of transcription
- start of transcription
Q: Answer the following question given this paragraph: In eukaryotic cells, the start of transcription is one of the most complicated parts of gene regulation. There may be many regulatory proteins and regulatory elements involved. Regulation may also involve enhancers. Enhancers are distant regions of DNA that can loop back to interact with a gene's promoter. Q: Which is one of the most complicated parts of gene regulation in eukaryotic cells? A:
Answer:
start of transcription
