Stimulus Summary

Conclusion/Judgment - You shouldn’t always buy education technology
Example 1 - Students did as well on a test who used toothpicks and string compared to those who used computers
Example 2 - Military personnel who trained on cardboard did as well on a test as those who used a high-tech simulator

Answer Anticipation

Principle (Strengthen) questions will generally draw a judgment in the conclusion that we need to justify by connecting that judgment to the details in the premises.
Here, the judgment is that one shouldn’t always purchase high-tech educational tools. Why not? Because there are at least some situations where students using them did no better on tests than students who prepped using low-tech means.
Let’s find an answer that connects these concepts! Don’t buy the high-tech stuff if something else works just as well.

Answer choices

  1. A
    One should use different Remaining source text redacted.
    Why choice A is not credited
    The argument doesn’t bring up engineers and the military as examples to show that different tools should be used in each situation. Both are used to highlight that the high-tech tools aren’t always more effective than the low-tech ones!
  2. B
    High–tech solutions to modern Remaining source text redacted.
    Why choice B is not credited
    Knowledgeable personnel implementing these technologies is out of scope as it’s not discussed in the stimulus. These two situations may or may not have featured such personnel!
  3. C
    Spending large sums of Remaining source text redacted.
    Why choice C is not credited
    The argument concludes that you shouldn’t always purchase technologically advanced educational tools, so this answer talking about such purchases being somewhat justified run counter to the conclusion.
  4. D
    One should not invest Remaining source text redacted.
    Why choice D matches the stem
    There are, apparently, other teaching tools that are as effective as the high-tech stuff, as is witnessed by the equivalent test results between students using the low- and high-tech tools. And toothpicks/string/cardboard are, without a doubt, cheaper than costly technologies. As such, this answer justifies a conclusion that the high-tech stuff shouldn’t be used, at least in the cases presented in the stimulus. This answer justifies the conclusion and is thus the correct answer.
  5. E
    One should always provide Remaining source text redacted.
    Why choice E is not credited
    First, the technology in question seems less like an educational material and more like an educational tool. But if we say that those two are close enough, we’d still end up seeing that this answer suggests providing students with both low- and high-tech tools, which runs counter to the conclusion.
