A
It is now easier to measure a piece of land in terms of acres than in terms of plowing time.
B
For modern purposes, newer methods provide a more accurate measure of land than plowing time does.
C
Some plots of land that would have been considered unequal by plowing-time measurements are of equal physical dimensions.
D
Modern measures of land were adopted when people realized that plowing time was an inadequate measure for some land uses.
E
The advent of diversified land uses made new measures of land necessary.
Researcher: Overhearing only one side of a cell-phone conversation diverts listeners’ attention from whatever they are doing. Hearing only part of a conversation leaves listeners constantly trying to guess what the unheard talker has just said. Listeners’ attention is also diverted because cell-phone talkers speak abnormally loudly.
Summary
Hearing only one side of a cell-phone conversation distracts a person from whatever they’re doing. Hearing only one person in a conversation results in listeners constantly trying to guess what the unheard person is saying. Cell-phone conversations distract listeners because people talking on a cell-phone are abnormally loud.
Strongly Supported Conclusions
When a person performing a task hears a cell-phone conversation, that person ends up distracted from whatever they’re doing.
A
The risk that a driver will cause an accident is increased when the driver is talking on a cell phone.
This answer is unsupported. We don’t know from the stimulus what the risk of accident is for any driver. Since we don’t know the baseline risk, we also can’t say that this risk increases.
B
When a driver hears a passenger in the driver’s vehicle talking on a cell phone, that detracts from the driver’s performance.
This answer is strongly supported. Hearing only one side of a cell-phone conversation distracts a person from whatever they’re doing. Since the driver is distracted, this detracts from their driving.
C
Overhearing one side of a conversation on a traditional telephone does not divert listeners’ attention from tasks at hand.
This answer is unsupported. The stimulus is limited to overhearing conversations being had over a cell-phone. We don’t know what the effects are from overhearing a conversation had over a traditional phone.
D
People who overhear one side of a cell-phone conversation inevitably lose track of their thoughts.
This answer is unsupported. We don’t know if these people lose track of their own thoughts, we just know that they become distracted from whatever they’re doing.
E
Conversing on a cell phone requires making more guesses about what one’s conversational partner means than other forms of conversation do.
This answer is unsupported. We don’t know what conditions are required for having a conversation via cell-phone.
A
The government sponsors at least some investigations of agricultural techniques that are considered likely to solve agricultural problems and do not use commercial products.
B
For almost any agricultural problem, there is at least one agricultural technique that does not use commercial products but that would solve that agricultural problem.
C
Investigations of agricultural techniques are rarely sponsored by individuals or by any entity other than private for-profit corporations or the government.
D
Most if not all investigations of agricultural techniques that use commercial products are sponsored by private for-profit corporations.
E
Most if not all government-sponsored agricultural research investigates agricultural techniques that do not use commercial products.
