[Q]: I can use this background: 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. Now, I have a new situation: Two people went to the eye doctor's office for an annual exam; James had farsightedness, while Bob had myopia. Answer this question please: Which person didn't have the eyeballs shorter than normal?
****
[A]: Bob

[Q]: I can use this background: Old age begins in the mid-60s and lasts until the end of life. Many people over 65 have retired from work, freeing up their time for hobbies, grandchildren, and other interests. Stamina, strength, reflex time, and the senses all decline during old age, and the number of brain cells decreases as well. The immune system becomes less efficient, increasing the risk of serious illnesses such as cancer and pneumonia. Diseases such as Alzheimer's disease that cause loss of mental function also become more common. Now, I have a new situation: Mary and Ann met after a long time. Mary was 70 and she was Ann's aunt. She had a number of health problems. Ann was 52 and quite healthy. Answer this question please: Which woman freed up less time for her grandchildren?
****
[A]: Ann

[Q]: I can use this background: During May, June, and July, the Northern Hemisphere is exposed to more direct sunlight because the hemisphere faces the Sun. The same is true of the Southern Hemisphere in November, December, and January. It is Earth's axial tilt that causes the Sun to be higher in the sky during the summer months, which increases the solar flux. However, due to seasonal lag, June, July, and August are the warmest months in the Northern Hemisphere while December, January, and February are the warmest months in the Southern Hemisphere. Now, I have a new situation: Bill has a friend that lives in New Zealand and he always gets confused about the weather and the seasons when they chat, because the Southern Hemisphere has different seasons than people from the Northern Hemisphere. Answer this question please: Which hemisphere is exposed to less direct sunlight in June?
****
[A]: Southern

[Q]: I can use this background: Marine pollution is a generic term for the entry into the ocean of potentially hazardous chemicals or particles. The biggest culprits are rivers and with them many agriculture fertilizer chemicals as well as livestock and human waste. The excess of oxygen-depleting chemicals leads to hypoxia and the creation of a dead zone.Marine debris, which is also known as marine litter, describes human-created waste floating in a body of water. Oceanic debris tends to accumulate at the center of gyres and coastlines, frequently washing aground where it is known as beach litter. Now, I have a new situation: Two countries had big rivers discharging in the same ocean. Finland was very aware of environmental pollution and acted accordingly, while Russian practiced conventional agriculture and used fertilizers. Answer this question please: Which country caused more livestock waste to reach into the ocean?
****
[A]:
Russia
