Hi experts,
I have been having major trouble in weaken questions. After trying all sorts of strategies stated in different books, although they helped a little, I am still getting them often wrong, So I tried to figure out my own. But I am not sure if this one will work with all sorts of weaken questions.
I will take an example from OG 11 and show how its done and may be someone could point out if this won't work for any case.
Dental researchers recently discovered that tooth-brushes can become contaminated with
bacteria that cause pneumonia and strep throatıThey found that contamination usually Occurs after
toothbrushes have been used for four weeks. For that reason people should replace their
toothbrushes at least once a month
Which of the following if true would most weaken the conclusion above?
(A) The dental researchers could not discover why toothbrush contamination usually
occurred only after toothbrushes had been used for four weeksı
(B) The dental researchers failed to investigate contamination of toothbrushes by viruses
yeasts and other pathogenic microorganisms
(C) The dental researchers found that among people who used toothbrushes contaminated
with bacteria that cause pneumonia and strep throat the incidence of these diseases was no higher
than among people who used uncontaminated toothbrushes
(D) The dental researchers found that people who rinsed their toothbrushes thoroughly in hot
water after each use were as likely to have contaminated toothbrushes as were people who only
rinsed their toothbrushes hurriedly in cold water after each use
(E) The dental researchers found that, after six weeks of useıgreater length of use of a
toothbrush did not correlate with a higher number of bacteria being present
Basically I take the conclusion and add a negation to it and a "therefore" in the front
Therefore, people should not necessarily replace their toothbrushes at least once a month
Then I try applying each choice by adding a "because" and see which ones strengthens the conclusion the most.
In OG , For most of the questions with simple stimulus, this is working 100% correctly. can someone suggest if i can continue using this one. Somehow its easy for me to strengthen a conclusion than weaken.
Most of the times when choices have lots of negations in them, and moreover if the stimulus has lot of negations I get completely confused and mess it up.
If this strategy doesn't seem right, please suggest me one.
I am just 7 weeks away from my D-day and I am still having a low accuracy for CR questions.
I have read the powerscore bible. Inspite of trying to apply the strategies, sometimes the stimulus appears very confusing and even in choices, when they add no's and not's, I end up selecting strengthen answers instead of weaken.
