Answer the following question given this paragraph: As you can see in the Figure above , the electric and magnetic fields that make up an electromagnetic wave are perpendicular (at right angles) to each other. Both fields are also perpendicular to the direction that the wave travels. Therefore, an electromagnetic wave is a transverse wave. However, unlike a mechanical transverse wave, which can only travel through matter, an electromagnetic transverse wave can travel through empty space. When waves travel through matter, they lose some energy to the matter as they pass through it. But when waves travel through space, no energy is lost. Therefore, electromagnetic waves don't get weaker as they travel. However, the energy is "diluted" as it travels farther from its source because it spreads out over an ever-larger area. Q: What may be lost when waves travel through matter, but not when they travel through space? A:
OPTIONS:
- matter
- frequency
- threshold
- energy

Answer: energy

Question: Answer the following question given this paragraph: Some benthos live near vents on the deep ocean floor. Tubeworms are an example ( Figure below ). Scalding hot water pours out of the vents. The hot water contains chemicals that some specialized bacteria can use to make food. Tubeworms have the bacteria living inside them. The bacteria get protection and the tubeworms get some of the food. Q: Give an example of benthos that live near vents on the deep ocean floor. A:
OPTIONS:
- amphipods
- crustaceans
- arthropods
- tubeworms
Answer: tubeworms

input with options: Answer the following question given this paragraph: Farsightedness, or hyperopia, is the condition in which distant objects are seen clearly, but nearby objects appear blurry. It occurs when the eyeball is shorter than normal (see Figure below ). This causes images to be focused in a spot that would fall behind the retina (if light could pass through the retina). Hyperopia can be corrected with convex lenses. The lenses focus images farther forward in the eye, so they fall on the retina instead of behind it. Q: What is the condition in which distant objects are seen clearly, but nearby objects appear blurry? A:
OPTIONS:
- synthesise , or hyperopia
- nearsightedness or hyperopia
- gleam , or hyperopia
- farsightedness, or hyperopia
output: farsightedness, or hyperopia

Q: Answer the following question given this paragraph: Vibrating objects such as drumheads produce sound energy. Q: Vibrating objects such as drumheads produce what? A:

OPTIONS:
- negative ions
- light
- heat
- sound energy

A: sound energy

input: OPTIONS:
- brain
- pancreas
- liver
- heart Now, answer this question: Answer the following question given this paragraph: Shock Hazards Electrical currents through people produce tremendously varied effects. An electrical current can be used to block back pain. The possibility of using electrical current to stimulate muscle action in paralyzed limbs, perhaps allowing paraplegics to walk, is under study. TV dramatizations in which electrical shocks are used to bring a heart attack victim out of ventricular fibrillation (a massively irregular, often fatal, beating of the heart) are more than common. Yet most electrical shock fatalities occur because a current put the heart into fibrillation. A pacemaker uses electrical shocks to stimulate the heart to beat properly. Some fatal shocks do not produce burns, but warts can be safely burned off with electric current (though freezing using liquid nitrogen is now more common). Of course, there are consistent explanations for these disparate effects. The major factors upon which the effects of electrical shock depend are 1. The amount of current. Q: A pacemaker uses electrical shocks to stimulate the what to beat properly? A:
A:
output: heart

Question: Answer the following question given this paragraph: Female Urethra The external urethral orifice is embedded in the anterior vaginal wall inferior to the clitoris, superior to the vaginal opening (introitus), and medial to the labia minora. Its short length, about 4 cm, is less of a barrier to fecal bacteria than the longer male urethra and the best explanation for the greater incidence of UTI in women. Voluntary control of the external urethral sphincter is a function of the pudendal nerve. It arises in the sacral region of the spinal cord, traveling via the S2S4 nerves of the sacral plexus. Q: The short length of what in women is the best explanation for the greater incidence of uti in women? A:
OPTIONS:
- vagina
- fallopian tube
- uterus
- urethra
Answer:
urethra
