input: OPTIONS:
- They are minor
- They occur rarely
- They are low temperature
- they move slowly Now, answer this question: Answer the following question given this paragraph: Effusive eruptions rarely kill anyone because they move slowly. People can usually be evacuated before an effusive eruption. Still, effusive eruptions can be destructive. There is not much anyone can do to stop a lava flow from destroying a building or road ( Figure below ). Q: Why do effusive eruptions rarely kill anyone? A:
A:
output: they move slowly

Answer the following question given this paragraph: Plant Parasites and Pathogens The production of sufficient good-quality crops is essential to human existence. Plant diseases have ruined crops, bringing widespread famine. Many plant pathogens are fungi that cause tissue decay and eventual death of the host (Figure 24.25). In addition to destroying plant tissue directly, some plant pathogens spoil crops by producing potent toxins. Fungi are also responsible for food spoilage and the rotting of stored crops. For example, the fungus Claviceps purpurea causes ergot, a disease of cereal crops (especially of rye). Although the fungus reduces the yield of cereals, the effects of the ergot's alkaloid toxins on humans and animals are of much greater significance. In animals, the disease is referred to as ergotism. The most common signs and symptoms are convulsions, hallucination, gangrene, and loss of milk in cattle. The active ingredient of ergot is lysergic acid, which is a precursor of the drug LSD. Smuts, rusts, and powdery or downy mildew are other examples of common fungal pathogens that affect crops. Q: Which is the active ingredient of cereal crop disease, ergot? A:

OPTIONS:
- byblis acid
- amino acid
- pixelation acid
- lysergic acid

Answer: lysergic acid

Problem: OPTIONS:
- greenhouse gases
- fracking disaster
- algal bloom
- oil spill
Q: Answer the following question given this paragraph: Oil spills are another source of ocean pollution. To get at oil buried beneath the seafloor, oil rigs are built in the oceans. These rigs pump oil from beneath the ocean floor. Huge ocean tankers carry oil around the world. If something goes wrong with a rig on a tanker, millions of barrels of oil may end up in the water. The oil may coat and kill ocean animals. Some of the oil will wash ashore. This oil may destroy coastal wetlands and ruin beaches. Figure below shows an oil spill on a beach. The oil washed ashore after a deadly oil rig explosion in the Gulf of Mexico in 2010. Q: A recent deadly explosion in the gulf of mexico exemplified what source of ocean pollution? A:
Answer: oil spill

Problem:OPTIONS:
- Stomach
- Liver
- Heart
- lungs

Answer the following question given this paragraph: Respiratory tree: terminates in alveolus, alveoli. Respiratory bronchioles branch into alveolar ducts and into alveoli. Alveolus: microscopic air sacs, 300 million of these in human lungs. Total surface area large. Gas diffuses micrometer, very tiny distance. Nervous System Composed of tissues designed to integrate sensory information and direct a coordinated response to the environment. Basic unit of the nervous system is the neuron1 , a highly specialized cell that uses both electrical and chemical processes to communicate. Neurons "listen" to sensory organs or other neurons, and can simultaneously "hear" from 1 to hundreds of inputs simultaneously. Likewise, a neuron can "talk" to other neurons or cells that can create an action, like muscle cells or glands. Neurons are outnumbered in the nervous system by glia. Glia were once thought to only play a supportive role in helping neurons survive; today we know that they also are important participants in the communication process. Glial cells include astrocytes, ependymal cells, and a cell that has a macrophage like function. There are also oligodendocytes and Schwann cells that provide a myelin sheath. Q: Alveoli can be found in which organ in the human body? A:
****
A: lungs

Answer the following question given this paragraph: attracted to the sites of infections in large numbers, and as they phagocytose the pathogens and subsequently die, their accumulated cellular remains are visible as pus at the infection site. Overall, inflammation is valuable for many reasons. Not only are the pathogens killed and debris removed, but the increase in vascular permeability encourages the entry of clotting factors, the first step towards wound repair. Inflammation also facilitates the transport of antigen to lymph nodes by dendritic cells for the development of the adaptive immune response. Q: What is the first step towards wound repair? A:
OPTIONS:
- electrolysis factors
- hormone factors
- blotting factors
- clotting factors
clotting factors

Answer the following question given this paragraph: When light is refracted its wavelength and speed change; however, its frequency remains the same as the frequency of the light source. Proof of this is that light retains its original color under water. For example, blue light is still blue under water. Q: Light retains its original color under water because what remains the same when light is refracted? A:
OPTIONS:
- wave length
- density
- sound
- frequency

Answer:
frequency
