Scientist: A number of errors can plague a data-collection process. Since examining the collected data enables researchers to detect many of these errors, it is standard practice for researchers to correct collected data. However, in my field, there is a striking tendency for such corrections to favor Jones’s theory; that is, the majority of corrections result in the corrected data’s being closer than the uncorrected data to what Jones’s theory predicts.

"Surprising" Phenomenon

Why do data corrections in the scientist’s field tend to favor Jones’s theory?

Objective

The right answer will be a hypothesis that explains why these data corrections gravitate towards what Jones’s theory predicts. The explanation must either signal that Jones’s theory is correct and errors naturally stray from the theory, or that those doing the data-corrections are themselves biased towards Jones’s theory.

A
Researchers normally give data that is in line with a theory the same weight as data that conflicts with that theory when they are determining whether to accept that theory.

If anything, it seems possible that researchers are giving data less weight when it strays from Jones’s theory. We also have no idea whether or not the theory has been accepted yet.

B
Researchers in the scientist’s field give data that conflicts with Jones’s theory greater scrutiny than they give data that is in line with Jones’s theory.

Researchers go looking for errors in data that conflicts with Jones’s theory. Data that falls in line with Jones’s theory, on the other hand, goes unremarked and uncorrected. This explains why data is corrected to align with Jones’s theory.

C
Researchers in the scientist’s field are more likely to pursue lines of research that they expect will favor theories they accept than to pursue other lines of research.

It doesn’t matter what researchers expect ahead of time. We need to know why their data-corrections align with Jones’s theory.

D
Even if researchers fail to detect errors in a data-collection process when they examine the data that they collected, that does not guarantee that no such errors exist.

This may be true, but why do researchers mainly detect errors that are then corrected to bring data in line with Jones’s theory? This doesn’t tell us enough about the data-correction process.

E
Researchers in the scientist’s field have formulated several other theories that attempt to explain the same range of phenomena that Jones’s theory attempts to explain.

Why do data-corrections favor Jones’s theory rather than these other theories? If anything, this only complicates things since we now know there are other theories to choose from.

Until fairly recently, classroom computers were considered a luxury. Today, educators argue that students who have not had training in computer skills will lack the skills necessary to compete in the global marketplace. However, studies show that schools emphasizing computer technology spend more time teaching computer skills but less time developing students’ basic math and reading skills.

Summary
Until recently, classroom computers were considered a luxury. Educators claim that students that have not been taught computer skills will lack necessary skills to compete in the global marketplace. However, studies show that schools that emphasize computer technology spend more time teaching computer skills than basic skills.

Strongly Supported Conclusions
Sometimes keeping up with the requirements for developing new skills can lead to neglect in addressing other skills.

A
A knowledge of the latest technologies is no more valuable than a knowledge of the fundamental academic disciplines.
This answer is unsupported. We don’t know, in direct comparison, what skills are more valuable than others. We know that computer skills are valuable to enable students to compete, but basic knowledge could be more valuable.
B
Schools cannot emphasize the teaching of computer skills without neglecting other skills.
This answer is unsupported. We don’t know if a scenario of balancing the attention between different skills is impossible. We only know that recent studies show that schools are not balancing them.
C
A complete rethinking of traditional academic subjects is required in order to keep pace with global developments.
This answer is unsupported. We don’t know whether a complete rethinking is required.
D
Attempting to keep pace with recent educational developments can result in neglecting basic skills in favor of other skills.
This answer is strongly supported. Studies show that schools are spending less time teaching the basics in favor of teaching computer skills to students.
E
Giving students a knowledge of new technologies should be the primary goal of education.
This answer is unsupported. We don’t know what should be the primary goal of education. The stimulus does not make a value judgment.

Godinez: In the past, land was sometimes measured by the amount of time required to plow it. Thus, two plots of equal physical dimensions were considered unequal if one was more difficult to plow than the other. However, knowing how long an area takes to plow reveals little about how many apartment complexes it can hold. Therefore, it became necessary to adopt new measures of land, such as acreage, when land uses diversified.

Summarize Argument
The author concludes that we needed to come up with new ways to measure the value of land when the uses to which the land was put became more diverse. As an example, if land is used for farming, then the time it takes to plow the land is relevant to the land’s value. But if the land is used for apartments, plow time isn’t useful.

Identify Conclusion
The conclusion is the author’s assessment of the need for a change in measurement of land value: “[I]t became necessary to adopt new measures of land ... when land uses diversified.”

A
It is now easier to measure a piece of land in terms of acres than in terms of plowing time.
The conclusion doesn’t assert anything about the ease or difficulty of measuring land value. It merely states that there was a need for new measures of land value.
B
For modern purposes, newer methods provide a more accurate measure of land than plowing time does.
This may be strongly supported by the argument, but it’s not the conclusion. The conclusion concerns how new measures are necessary. It’s not about the accuracy of particular measurements of land value.
C
Some plots of land that would have been considered unequal by plowing-time measurements are of equal physical dimensions.
This relates only to the context in the first two sentences. The author’s conclusion concerns the necessity of adopting new measures of value.
D
Modern measures of land were adopted when people realized that plowing time was an inadequate measure for some land uses.
This doesn’t capture the author’s claim in the conclusion that new measures were “necessary.” The author wasn’t just saying that modern measures were adopted after plowing-time became inadequate. He was also asserting that we were required to adopt new methods.
E
The advent of diversified land uses made new measures of land necessary.
This paraphrases the conclusion. The “advent of diversified land uses” matches with “when land uses diversified,” and “made new measures of land necessary” matches with “it became necessary to adopt new measures of land.”
