Zorluk: KolayIdentifying Necessary Assumptions

To increase productivity, a software company is mandating a switch from traditional keyboards to new ergonomic keyboards for all its programmers. The manufacturer of the ergonomic keyboards has proven that they reduce typing strain by 40 percent. Therefore, the company's programmers will definitely produce more code per week after the switch.

Which of the following statements are necessary assumptions required by the argument? (Select all that apply)

  1. Typing strain is currently a factor that limits the amount of code the programmers can produce.Cevap
  2. B
    The new ergonomic keyboards are the most effective method available for reducing programmer typing strain.
  3. C
    All programmers at the company currently suffer from severe typing strain.
  4. The programmers will not experience a decrease in typing speed that entirely offsets the benefits of the reduced strain.Cevap
  5. E
    Programmers at this software company type faster on average than those at competing software companies.

Cevap

The argument necessarily assumes that typing strain currently limits code production and that negative factors (like a decrease in typing speed) will not completely offset the benefits of the new keyboards.
The correct statements bridge the critical gaps in the argument. First, for a reduction in typing strain to increase code output, typing strain must actually be a limiting factor in the current workflow. Second, introducing a new tool must not introduce new inefficiencies (like slower typing speeds) that cancel out the promised benefits. If either of these statements is logically negated, the conclusion that programmers will 'definitely produce more code' collapses.

Adım Adım Çözüm

1
Identify the core argument structure.
Premise: Ergonomic keyboards reduce typing strain by 40%. Conclusion: Programmers will produce more code per week.
Understanding the premise and conclusion is required to spot the logical gaps.
2
Determine the logical gaps between the premise and the conclusion.
The argument assumes that reducing typing strain directly causes an increase in code production, and that introducing new keyboards won't cause other problems.
An argument's conclusion only follows if all missing links are accounted for.
3
Apply the Negation Technique to the answer choices.
Negating the correct options causes the argument to logically collapse. For example, if typing strain does NOT limit code production, the conclusion fails.
The Negation Technique is the definitive test for a necessary assumption.
