Q: Q: What do doctors call farsightedness or the inability to see close objects clearly? Read this paragraph and choose the correct option from the provided answers: Farsightedness is also known as hyperopia . It affects about one fourth of people. People with hyperopia can see distant objects clearly, but nearby objects appear blurry. In hyperopia, the eye is too short. This results in images being focused in back of the retina ( Figure above ). Hyperopia is corrected with a convex lens, which curves outward like the outside of a bowl. The lens changes the focus so that images fall on the retina as they should. Choices: - hypopia - dysarthria - myopia - hyperopia A:
A: hyperopia

Q: Q: What is the name given to the use of controlled nuclear fusion as an energy source? Read this paragraph and choose the correct option from the provided answers: 32.5 Fusion While basking in the warmth of the summer sun, a student reads of the latest breakthrough in achieving sustained thermonuclear power and vaguely recalls hearing about the cold fusion controversy. The three are connected. The Sun's energy is produced by nuclear fusion (see Figure 32.15). Thermonuclear power is the name given to the use of controlled nuclear fusion as an energy source. While research in the area of thermonuclear power is progressing, high temperatures and containment difficulties remain. The cold fusion controversy centered around unsubstantiated claims of practical fusion power at room temperatures. Choices: - generator power - half-life - fossil fuel - thermonuclear power A:
A: thermonuclear power
