input with options: Answer the following question given this paragraph: Although the idea that Earth is a magnet is centuries old, the discovery of why Earth is a magnet is a relatively new. In the early 1900s, scientists started using seismographic data to learn about Earth's inner structure. A seismograph detects and measure earthquake waves. Evidence from earthquakes showed that Earth has a solid inner core and a liquid outer core (see the Figure below ). The outer core consists of molten metals, mainly iron and nickel. Scientists think that Earth's magnetic field is generated by the movement of charged particles through these molten metals in the outer core. The particles move as Earth spins on its axis. The video at the URL below takes a closer look at how this occurs. Q: What device detects and measuresee earthquake waves? A:
OPTIONS:
- stenograph
- polygraph
- sphygmomanometer
- seismograph
output: seismograph

Q: Answer the following question given this paragraph: When appropriate, a symbol may be written above or below the arrow to indicate some special circumstance. The symbol "" is often used to indicate that the reaction is to be heated. Q: Which enzyme is used in step three of the polymerase chain reaction because of it's ability to withstand high temperatures? A:

OPTIONS:
- minocycline polymerase
- carbon polumerase
- backronym polymerase
- taq polymerase

A: taq polymerase

input: OPTIONS:
- low thyroid levels
- high fat diets
- high serotonin levels
- low serotonin levels Now, answer this question: Answer the following question given this paragraph: Some people have low levels of the neurotransmitter called serotonin in their brain. Scientists think that this is one cause of depression. Medications called antidepressants help bring serotonin levels back to normal. For many people with depression, antidepressants control the symptoms of their depression and help them lead happy, productive lives. Q: What according to scientists is the major cause of depression? A:
A:
output: low serotonin levels

Answer the following question given this paragraph: Amphibian skin contains keratin, a protein that is also found in the outer covering of most other four-legged vertebrates. The keratin in amphibians is not too tough to allow gases and water to pass through their skin. Most amphibians breathe with gills as larvae and with lungs as adults. However, extra oxygen is absorbed through the skin. Q: Most amphibians breathe with these as larvae? A:

OPTIONS:
- nostrils
- lungs
- pores
- gills

Answer: gills

Problem: OPTIONS:
- giving cells
- neutral cells
- innoculous cells
- cancer cells
Q: Answer the following question given this paragraph: Cancer and Epigenetic Alterations Silencing genes through epigenetic mechanisms is also very common in cancer cells. There are characteristic modifications to histone proteins and DNA that are associated with silenced genes. In cancer cells, the DNA in the promoter region of silenced genes is methylated on cytosine DNA residues in CpG islands. Histone proteins that surround that region lack the acetylation modification that is present when the genes are expressed in normal cells. This combination of DNA methylation and histone deacetylation (epigenetic modifications that lead to gene silencing) is commonly found in cancer. When these modifications occur, the gene present in that chromosomal region is silenced. Increasingly, scientists understand how epigenetic changes are altered in cancer. Because these changes are temporary and can be reversedfor example, by preventing the action of the histone deacetylase protein that removes acetyl groups, or by DNA methyl transferase enzymes that add methyl groups to cytosines in DNAit is possible to design new drugs and new therapies to take advantage of the reversible nature of these processes. Indeed, many researchers are testing how a silenced gene can be switched back on in a cancer cell to help re-establish normal growth patterns. Genes involved in the development of many other illnesses, ranging from allergies to inflammation to autism, are thought to be regulated by epigenetic mechanisms. As our knowledge of how genes are controlled deepens, new ways to treat diseases like cancer will emerge. Q: Silencing genes through epigenetic mechanisms is commonly practiced on what type of uncontrolled cells? A:
Answer: cancer cells

Answer the following question given this paragraph: The Animal Kingdom is one of four kingdoms in the Eukarya Domain. The Animal Kingdom, in turn, is divided into almost 40 modern phyla. The Animal Kingdom can also be divided into two basic groups: invertebrates and vertebrates. Most animal species are invertebrates, which lack a backbone. Q: The animal kingdom can also be divided into two basic groups, what are they? A:

OPTIONS:
- mammals and fish
- aquatic and land
- sponges and vertebrates
- invertebrates and vertebrates

Answer:
invertebrates and vertebrates
