THEORIES OF WEAKEN QUESTIONS:- Weakening does not mean destroying.You do not need to find an answer that destroys the conclusion. Instead, you just need to find an answer that hurts the argument.
- Information (both assumption and conclusion) in the argument is questionable. KEY POINT. Never assume information in the stimulus is correct. (if it’s correct, how can you weaken?)HOW DO YOU WEAKEN AN ARGUMENTWhen you hear an argument, critically, you should ask yourself;
- The information (conclusion & assumption) is correct?
- The information in the argument is complete?
- The comparison in the argument is correct?
- The condition leading to a conclusion can happen?
- …………………….ANALYZE THE QUESTION:Fact: Electric razors recently introduced a new model that offered various features that ensured a degree of precision not possible with older models.
Fact: After a year on the market, the new model proved to sell poorly compared to its older counterparts,
Conclusion: Precision was not an important concern for consumers.
Counter conclusion: However, this view was seriously challenged by a later finding that ___________________.
Pre-thinking: The company said that: The new electric razors ensured a degree of precision not possible with older models. After weak sales, it concluded that precision was not an important concern for consumers.
What was its assumption?. The company assumed the electric razor is more precise than the older one. You can confirm this assumption by negating the assumption: The company assumed the electric razor is NOT more precise than the older one ==> Clearly, the conclusion is not correct.
But
DO NOT assume this assumption is correct. KEY POINT. If it's correct, the conclusion is correct too. How can you weaken it?
ANALYZE EACH ANSWER:a) Around the time the new razor was unveiled, a consumer guide reported that many shoddy haircuts and shaves were the result of faulty precision features in razors.
Wrong. Out of scope. A talks about “razors” in general, but we need to focus on the razors (older version and new electric razor) of the company.
b)Razor users typically find that they
get the best results from older razors because they are most familiar with their features.
Correct. B
hurts the argument. (not destroy) The conclusion was based on the assumption – new electric razor is more precise than the old one. Important note is
information in the stimulus is questionable, you cannot assume the new razor is more precise than the old razor. What if the new razor is
NOT more precise than the old razor? Customers chose to use the old one just because it’s more precise and provided
best results. Clearly, precision is an important concern for customers. Hence, B
hurts the conclusion and is correct.
In addition,
because of the word "familiar", so B is correct. Let see why. Assume you have a new electric razors with advanced features, but you are not familiar to it (you do not know how to use it properly). Do you think you can shave precisely?
"Precision" is not the characteristic of the razor itself. "Precision" only makes sense if you can use the razor properly and it provides best results (I highlighted the phrase "best results" in my explanation). The precision depends on whether the user is familiar to the razor. That's the KEY. If the user is not familiar, the new electric razor CANNOT provide the precision.
Thus, B is the correct answer.
c)The company does a significant part of its business with hair salons and barber shops, which are frequented by people who do not own electric razors themselves.
Wrong. Out of scope. The fact that hair salons and barber shops are frequented by people who do not own electric razors does not weaken the conclusion at all.
d)Despite the addition of new precision features on the new razor model, the razor did not significantly increase in price.
Wrong. Out of scope. Price does not play any role here.
e)Other razor-making companies introduced new models with similar precision features, and these went on to sell relatively well.
Wrong. TEMPTING. You do not have enough information to conclude that those companies had good sales because of “similar precision features”. What if those company sold their razors well because their prices were cheaper, or because their marketing campaigns were better. Hence, E cannot be the answer.
Hope it helps.
