LR Question 10 Explanation

QUESTION TEXT: Double-blind techniques should be used whenever possible…

QUESTION TYPE: Identify the Conclusion

CONCLUSION: We should use double-blind techniques in experiments as much as we can.

REASONING: Double-blind techniques prevent misinterpretations. Misinterpretations are bad.

ANALYSIS: If an argument says “should”, then that sentence is usually the conclusion. The second sentence is evidence: it provides reasons why we should use double blind techniques.

___________

1. This is a fact supporting the idea that we should use double-blind techniques. Double blind techniques help prevent such bias.
2. CORRECT. This is the first sentence. You can tell it’s the conclusion because it says “should”, and because the second sentence provides support by showing why double-blind experiments are good.
3. The argument didn’t actually say this, so this can’t be the conclusion.. (Considering bias isn’t the same as a double blind experiment. You might consider the risk of bias and yet still fall prey to bias.)
4. This is evidence supporting the conclusion that scientists should use double-blind techniques. Double-blind techniques help avoid this sort of misinterpretation.
5. The argument didn’t actually say double-blind techniques can ensure objectivity. The author merely said they help. In any case, the real conclusion is that scientists should use such techniques.
