CR 9/8/07:
Two specific ways to weaken:
1) Provide alternative explanation
2) Weaken the analogy is an analogous situation is put forth
9/13/07:
Assumptions - are premises that must support conclusion
--> eliminate choices that do not support conclusion (out of scope/irrelevant)
--> assumption must be true
LOOKOUT - for keywords that qualify/limit/narrow a statement - they can narrow the scope of the conclusion and provide a way to attack argument
--> "the company will see an IMMEDIATE cost benefit"
--> show that the company's benefit will not be immediate
WATCH OUT - for answer choices that simply restate a premise
stimulus: "...country x has experienced similar conditions"
answer choice: "both have experienced drought conditions"
CONTRADICTIONS - if an answer choice contradicts a premise, it is most likely wrong since premises must be true.
#101 CR OG11 (inference type)
"...but such an action would be likely to cause international discord" <-- premise!
(b) "As long as international opinion is unanimously against patria..." <-- unanimously implies agreement but premise states there will be discord
(e) "for a blockade of Patria's ports to be successful, international opinion must be unanimous"
TIME WASTER - rereading question stems that are long in order to fully understand what is being asked
--> look for the basic question type and go straight to the stimulus
--> long question stems often appear in stimuli with two opposing sides and you are asked to look for something relating to one side
Assumptions - premise must not be out of scope
--> e.g. "Sandactulus" and birds
--> answer choice: "...all creatures that fly..." (addresses more animals than stimulus discusses)
Statistics - watch out for stimuli with rates/percents/totals
--> focus only on the quantity that is relevant
--> #92 OG11 : ....10 cents per miles
(b)...the total number of trips...
(c) .. avg length of trips
(e) ...total distance...(correct...stimulus deals with money and distance)
Assumptions - Eliminate answer choices that presuppose conclusion. Assumption supports conclusion - the conclusion cannot already be true.
Statistics - Note the difference between a specific portion of a larger population vs the average for that population --> the specific portion is included in the calculations for the average
--> #103 OG11: "...the average life span [of Louisianans]"
(c) 25% of all Louisianans
(d) average life expectancy has risen
-->both are included in the calculations used to determine avg
REMEMBER - on long arguments with multiple sentences, do not overlook beginning sentences as crucial information is sometimes provided
WEAKEN - another important way to weaken (usually found on hard CR): weaken assumptions presupposed by argument
--> harder because you must find the assumption first then weaken it.
