A
Because of technological innovation, most workplaces in the high-risk industries do not require as much unprotected interaction between workers and heavy machinery as they did in 1955.
B
Most of the work-related injuries that occurred before 1955 were the result of worker carelessness.
C
The annual number of work-related injuries has increased since the legislation took effect.
D
The number of work-related injuries occurring within industries not considered high-risk has increased annually since 1955.
E
Workplace safety conditions in all industries have improved steadily since 1955.
Economist: Historically, sunflower seed was one of the largest production crops in Kalotopia, and it continues to be a major source of income for several countries. The renewed growing of sunflowers would provide relief to Kalotopia’s farming industry, which is quite unstable. Further, sunflower oil can provide a variety of products, both industrial and consumer, at little cost to Kalotopia’s already fragile environment.
Summary
Sunflower seed was one of the largest production crops in Kalotopia. Sunflower seed is a major source of income for many countries. Renewing the growth of sunflower seeds in Kalotopia would help its unstable farming industry. Sunflower oil can provide a variety of industrial and consumer products at little cost to the environment. Kalotopia has a fragile environment.
Strongly Supported Conclusions
A former production crop in Kalotopia could help the farming industry if it were grown again.
A
Kalotopia’s farming industry will deteriorate if sunflowers are not grown there.
This is unsupported because we don’t know that the industry will get worse without the sunflowers. We only know that it is currently unstable.
B
Stabilizing Kalotopia’s farming industry would improve the economy without damaging the environment.
This is unsupported because while we know that the cost to the environment would be little, but not necessarily zero.
C
Kalotopia’s farming industry would be better off now if it had never ceased to grow any of the crops that historically were large production crops.
This is unsupported because we don’t know whether Kalotopia had important reasons for ceasing sunflower production in the past that made the country better off than if it had continued sunflower production.
D
A crop that was once a large production crop in Kalotopia would, if it were grown there again, benefit that country’s farmers and general economy.
This is strongly supported because the author states that growing sunflower seed, which used to be a large production crop, would benefit farmers and create new products.
E
Sunflower seed is a better crop for Kalotopia from both the environmental and the economic viewpoints than are most crops that could be grown there.
This is unsupported because the author never compares sunflower seed to other possible crops that may be able to solve the instability just as well.
A
Scientists do not fully understand what brought about the changes in the electric current in the earth’s crust that preceded each of the major quakes in the region over the last ten years.
B
Most other earthquake prediction methods have been based on a weaker correlation than that found between the changes in the electric current in the earth’s crust and the subsequent earthquakes.
C
The frequency of major earthquakes in the region has increased over the last ten years.
D
There is considerable variation in the length of time between the changes in the electric current and the subsequent earthquakes.
E
There is presently only one station in the region that is capable of detecting the electric current in the earth’s crust.
A
Whenever machines are dependent on other machines of the same type, competition among manufacturers is damaging to the industry.
B
In some industries it is in the interest of competitors to cooperate to some extent with one another.
C
The more competitors there are in a high-tech industry, the more they will have to cooperate in determining the basic design of their product.
D
Some cooperation among manufacturers in the same industry is more beneficial than is pure competition.
E
Cooperation is beneficial only in industries whose products depend on other products of the same type.
A
The expense of television advertising slots makes it crucial for companies to target people who are most likely to purchase their products.
B
Advertising slots during news programs almost always cost far less than advertising slots during popular sitcoms whose leading characters are young adults.
C
When television executives decide which shows to renew, they do so primarily in terms of the shows’ ratings among people aged 25 and under.
D
Those who make decisions about television advertising believe that people older than 25 almost never change their buying habits.
E
When companies advertise consumer products in print media, they focus primarily on people aged 26 and over.
Note: The usage of "almost every Wednesday" here is ambiguous. It's unclear whether it's meant to include or exclude every Wednesday. I can see a reasonable disagreement. But the point is that it doesn't matter. The LSAT does not trade on the kind of ambiguity that gives rise to reasonable disagreements. See, if you want to interpret inclusive, then that's how the video lesson does it too and you get to the right answer choice. By default, you are taught in the Core Curriculum to interpret "most" inclusively.
Now what if you want to interpret exclusive? Okay, let's do it. You'll see that this won't change anything about the right or wrong answers.
Exclusive interpretation of "almost every Wednesday is a free poetry reading day" means that it does NOT include every Wednesday. In other words, on some Wednesdays there are no free poetry readings. Okay, so let's translate this to:
W -(e)m-> free poetry reading -> 1/2$ coffee
"-(e)m->" means "exclusive most" as opposed to
our standard "-m->" which means "inclusive most"
Therefore, what's the relationship between Wednesday and 1/2$ coffee?
W -(e)m-> 1/2$ coffee or
W -m-> 1/2$ coffee
I mean, we know most Wednesdays are 1/2$ coffee days. Really the question is whether we can say for sure that there are Wednesdays on which Zack's does not offer 1/2$ coffee. You might say, well, we do have some Wednesdays where there are no free poetry readings. Okay. And on those days... what's the price of coffee?
We don't know. They could well be 1/2$ coffee for some other reason. Because it could well be that Zack's is just crazy about offering 1/2$ coffee all day every day. Because Zack is just a great guy.
Even under the exclusive most interpretation, what (D) says still Must Be True. Zack's offers 1/2$ coffee all day on most Wednesdays, possibly all Wednesdays. Indeed it must be true that it's possible. Answer (E) is still at best a Could Be True. We just don't know that there are some Wednesdays on which coffee is more than 1/2$.
