Question: Answer the following question given this paragraph: Chemistry in Everyday Life Transition Metal Catalysts One of the most important applications of transition metals is as industrial catalysts. As you recall from the chapter on kinetics, a catalyst increases the rate of reaction by lowering the activation energy and is regenerated in the catalytic cycle. Over 90% of all manufactured products are made with the aid of one or more catalysts. The ability to bind ligands and change oxidation states makes transition metal catalysts well suited for catalytic applications. Vanadium oxide is used to produce 230,000,000 tons of sulfuric acid worldwide each year, which in turn is used to make everything from fertilizers to cans for food. Plastics are made with the aid of transition metal catalysts, along with detergents, fertilizers, paints, and more (see Figure 19.26). Very complicated pharmaceuticals are manufactured with catalysts that are selective, reacting with one specific bond out of a large number of possibilities. Catalysts allow processes to be more economical and more environmentally friendly. Developing new catalysts and better understanding of existing systems are important areas of current research. Q: What happens if a catalyst runs out? A:
OPTIONS:
- variety slows
- variety increases
- reaction increases
- reaction slows
Answer: reaction slows

input with options: Answer the following question given this paragraph: There is a lot of volcanic activity at divergent plate boundaries in the oceans. As the plates pull away from each other, they create deep fissures. Molten lava erupts through these cracks. The East Pacific Rise is a divergent plate boundary in the Pacific Ocean ( Figure below ). The Mid-Atlantic Ridge is a divergent plate boundary in the Atlantic Ocean. Q: In what ocean is the mid-atlantic ridge located? A:
OPTIONS:
- indian ocean
- pacific ocean
- arctic ocean
- atlantic ocean
output: atlantic ocean

Q: Answer the following question given this paragraph: Human Genome, Chromosomes, and Genes. Each chromosome of the human genome contains many genes as well as noncoding intergenic (between genes) regions. Each pair of chromosomes is shown here in a different color. Notice that there are 23 pairs of chromosomes. Q: How many pairs of chromosomes do human have ? A:

OPTIONS:
- 12 pairs
- 31 pairs
- 19 pairs
- 23 pairs

A: 23 pairs

input: OPTIONS:
- amoeba
- ecosystems
- parasites
- pathogens Now, answer this question: Answer the following question given this paragraph: STIs are diseases caused by pathogens that spread through sexual contact. Abstinence from sexual activity and other risk behaviors is the only completely effective way to prevent the spread of STIs. Q: Stis are diseases caused by what that spread through sexual contact? A:
A:
output: pathogens

Answer the following question given this paragraph: A small child darts in front of your bike as you race down the street. You see the child and immediately react. You put on the brakes, steer away from the child, and yell out a warning, all in just a split second. How do you respond so quickly? Such rapid responses are controlled by your nervous system. The nervous system is a complex network of nervous tissue that carries electrical messages throughout the body. It includes the brain and spinal cord, the central nervous system , and nerves that run throughout the body, the peripheral nervous system (see Figure below ). To understand how nervous messages can travel so quickly, you need to know more about nerve cells. Q: What is the complex network of nervous tissue that carries electrical messages throughout the body? A:

OPTIONS:
- respiratory system
- circulatory system
- lymphatic system
- nervous system

Answer: nervous system

Q: Answer the following question given this paragraph: Your sense of taste is controlled by sensory neurons , or nerve cells, on your tongue that sense the chemicals in food. The neurons are grouped in bundles within taste buds . Each taste bud actually has a pore that opens out to the surface of the tongue enabling molecules and ions taken into the mouth to reach the receptor cells inside. There are five different types of taste neurons on the tongue. Each type detects a different taste. The tastes are:. Q: How many different types of taste neurons does the tongue contain? A:

OPTIONS:
- four
- three
- ten
- five

A:
five
