PROBLEM: Background 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. 
Story: Two siblings Jane and Matt, needed eyeglasses. Matt was nearsighted, while Jane was farsighted. they bought themselves two nice pairs of eyeglasses. 
Question: Which sibling had a difficulty seeing distant objects?

SOLUTION: Matt.

PROBLEM: Background Paragraph: Carbon monoxide is used in modified atmosphere packaging systems in the US, mainly with fresh meat products such as beef, pork, and fish to keep them looking fresh. The carbon monoxide combines with myoglobin to form carboxymyoglobin, a bright-cherry-red pigment. Carboxymyoglobin is more stable than the oxygenated form of myoglobin, oxymyoglobin, which can become oxidized to the brown pigment metmyoglobin. This stable red color can persist much longer than in normally packaged meat. Typical levels of carbon monoxide used in the facilities that use this process are between 0.4% to 0.5%. 
Story: Mike went to his local grocery store. He noticed that meats had two different packaging, product A and product B. When he looked closely, he found that in product A packaging carbon monoxide was used, but in product B carbon monoxide was not used. He asked the store clerk what difference it made. 
Question: Would product A look red longer or shorter than product B?

SOLUTION: longer.

PROBLEM: Background Paragraph: During late adulthood, the risk of developing diseases such as cardiovascular diseases and cancer continues to rise. Most people also have a decline in strength and stamina. Their senses may start failing, and their reflex time typically increases. Their immune system also doesn’t work as well as it used to. As a result, common diseases like the flu may become more serious and even lead to death. The majority of late adults develop arthritis, and as many as one in four develop Alzheimer’s disease.
