Question 6
1. Spot the question stem : If " the answers assumed ", most strongly supports the argument of the question
2. Question type: Sufficient assumption - principle.
3. Tactics analyze:
a. Bridge the conditional logic chains if there is any - ( the new concept from the conclusion to the premises. )
b. If A, then B, and B is the argument of the question. Then If No B, then No A ( Slightly different tactics versus the negate tactics to the questions type of necessary assumption, but the core concept is the same. )
So, negate the the argument of the original question and to see if the negate version of the original argument could be sufficient enough to guarantee the negate version of every question answer to see if answer is necessary.
4. Looking for the premises and conclusions
P1: Cigarette smoking has been shown to be a health hazard.
Inference: CS ---> HeHa
C: Government should ban all advertisement that promote smoking
Inference: Promote smoking ---> Government ban the advertisement
why promote smoking should be banned ? Because smoking cigs shows to be a health hazard.
Cigs smoking ---> Health Hazard ---> promote smoking ---> ban the advertisement
So, Health hazard ---> Ban the advertisement
No Ban the advertisement ---> No Health Hazard. ( Perfectly match with our E option )
A. Show people of doing something does not mean that people must be doing that thing. If People would not be doing the things shown by the advertisement, then even though the thing itself causes health issue, people still would not be affected by it, and if people would not be affected by it, it would be reasonable to ban advertisement the promote smoking.
B. There is no any info nor any reasoning steps involving " mislead "
C. Regardless of the fact that it disclose the health hazards associate to the products they promote, it won't really affect the argument.
D. Regardless of the fact that whether they confirm to the strict government heathl and safety standards, it would not be matter to the point of whether should the government ban it or not.
E. Perfect answer.
Question of Calories
1. Spot the question type - If " the answer is assumed ", then the original argument must be weakened
2. Question type - Sufficient assumption + Weaken
3. Tactics:
a. Bridge
b. Double - Negate.
4. Looking for the premises and conclusions:
C: Labeling high calorie food as sugar free ---> Replacement of all sugar by artificial sweeteners ---> Prohibit by law.
P1: Consumer who need to lose weight ---> Interpret the label of sugar free as low in calories ---> harm themselves --- > building weight loss diets around foods label sugar free.
P2: Manufacturers of sugar free foods are well aware of this tendency.
Inference: False interpretation of " sugar free " as " low in calories " ---> harm Consumers ---> Label of " sugar free " should be prohibited.
ok, so in order to weaken it, we need to find an answer to support of the negate version of the last part of the inferred logical chain - Label of " sugar free " should not be prohibited.
Since the principle of the argument is, as long as the consumer would be harm, and manufacturers knows the tendency well, we have to find the answer that best support of a point that " why it would harm the consumer, if we prohibited. "
A.Regardless of the fact that whether they would respond to a ban on the label of sugar free by reducing the calories in sugar free products by enough to be able to promote those products as diet foods does actually strengthen the argument but not weaken the argument ( Which is to say, the argument is convincing, so they would respond ).
B. Be careful, Individual who are diabetic does not 100% represent of the group of the consumer who needs to lose weight. However, as long as there are slightly chances that individual who are diabetic are also the consumers who also needs to lose weight, then by prohibiting the label of " sugar free" would definitely harm the customers. Correct answer.
C. Sometimes = At least one.
If consumer are none at once slow to notice changes, the changes must be well advertised.
Which is to say, they could normally or fast to notice the changes only if the changes must be well advertised. However, whether they could notice the changes or not does not really relevant whether the label should be banned or not nor whether the customer would be harm or not.
D. Totally non relevant
E. One thing mentioned does not have the same effects on the outcome as the other thing does, the fact that does not prove whether that one thing does not the effects on the outcome.
Question12
Spot the question type: If argument in the statement is true, then one of the following answer must also be true "
Question type: Necessary assumption - Must be true.
Tactics analysis:
A. If A, then B, So If no B, then No A. As a result, If no B can't not guarantee the necessary being of No A, then B itself does no need to be necessary. So, We are looking for the answer : If No B ( answer ), the A.
The premises and conclusion in the question
* Young to the left = from left to right
P1: All M ---- All T P2: ( 1 - 49 )/100 S ---- All M ---- ( 50 - 99 )/ 100 S P3: All DW ---- All M
Inferences:
1. All T must be order than All Dw, and some ( 1- 49) of the S, since All T are order than all M, and all m are order than some ( 1 - 49 ) S.
2. ( 50 - 99 )/100 S must be older than all DW, since All M are order than all DW.
However, regarding the ages between ( 50 - 99 )/100 S and All T, we dont have any evidences to prove the which one is either younger or older.
Let us dive into the options and start to negate the logical stand of each answer to see if the answer itself is necessary enough.
1. Negate: No Dw are as old as the youngest tulip tree. Does it overturn any part of the logic chains we have ?
Apparently no, no dw are as old as the youngest tulip tree could mean all dw are all older or younger than youngest tulip trees. ( however, it should not be all older )
2. Negate: No dw are as old as the ( 1 - 49 )/100 S. We know that All M must be older than ( 1 - 49 )/100 S, and All M must be older than all DW. However, we do not know the relationship between All Dw and ( 1 - 40 )/100 S.
3. Negate: No S are not as old as the oldest DW. So based on the negate logic, Some S must be either in the same age as the oldest DW ( Could be true , since ( 50 - 99 ) / 100 S must be older than all M, and All M must be older than all DW ) or some S must be younger than the oldest DW ( could be true , since ( 50 - 99 ) / 100 S must be older than all M, and All M must be older than all DW ). So, the negate of the answer choice C is not sufficient enough to lead to any necessary scenarios of the negate versions of original logic chains.
4. negate: No T are not as old as oldest S. Ok, since we only do know that All T and ( 50-99)/100 s must be order than all m; however, based on our inference 2, we know that the relationship between all T and ( 50-99)/100 S is not clear stated. As result, for both possible scenarios that all t are older than oldest S and All T are younger than oldest S, are not sufficient enough to negate the logic chain inferred above.
5. Negate: No S are not as old as the youngest T
Ok, It's either all S are all older than youngest T ( perfectly refute the original logic chains ) or All S are all younger than youngest T ( We are not certain, but we know that ( 1-49)/100 must be younger than youngest T ). And if the negate version of E could be set as, If no B ( Scenario A or Scenario B, but not both ) happened, then no A. Then apparently, Scenario A successfully guarantee No A is necessary. Correct answer.
Question 24:
1. Spot the question type : Necessary Assumption
2. Tactics analysis : Negate ( Defender )
3. Spot the premises and conclusions from the questions:
P1: D always repay her political debts asap.
P2: Lee wants the job for a long time and D owes lee a lot for his support in the last election
C: D will appoint lee to be the new head of the arts commission
Argument:
If ( a person want a job from D ) + ( D owes lee political debt ), then D will appoint that person as new head of the arts commission.
Contrapositive: If D will not appoint a person as new head of the arts commission, then it must be either that person does not want a job from d for a long time or D does not owe that person political debt or both.
A: Negate: D does have political debit that is both of longer stand then the one she owes to lee and could as suitably be repaid by an appointment to be the new head of the arts.
If D needs to pay the political debt asap and there is a higher debit D has to pay, then lee must not be the first person to be paid back with, and If there is a a person long standing for being suitable be paid by an appointment to be the new head of arts, then for sure, Lee will " not " be appointed as the arts commission.
Correct answer.
B. Negate: There is at least one to whom D owes a greater political debt for support in the last election than the political debt she owes to lee. ok, we know D must pay back the political debt asap; however, does the person could be paid back appropriately by being appointed as art commission ? Can't determine.
C. Lee is not " the only " person that D owes political debt who be willing to accept an appointment from her as the new head of the arts commission.
Ok, even we do have Susan, Tom, Greg, and Chen are all owed by D and all be willing to accept an appointment as the end of the arts commission, can we be 100% certain that Lee would " not " be appointed ?
No
D. Whether Lee is qualified to be appointed is " relevant " to D's decision.
SO ? Does Lee would not be appointed because D decide to check his qualifications ?
E. Negate: It is not the only way to repay the political debt to lee by appointment him as the head of the arts commission.
So? we still can't not eliminate the chance that Lee would " not " be appointed as the art commission even D still does have other options for him, and what if he does not like the other offerings ?
Question 9
Spot the question type: Flaw
Spot the premises and conclusion
P1: All announcement authorized by the head of the department is important
( all announcement authorized by the head of the department ) ---> Important
( Not important ) ---> ( no announcement authorized by the head of the department )
P2: Announcements ---( Sometimes ) --- > issues without authorization by people other than the head of the head of the department.
C: Some announcements will inevitably turn out not to be important.
Apparently
If A, then B. And now, author presumed the lacking of the sufficient condition will certain lead to the happenings of lacking the necessary condition of which ( Mistaken Negate )
Well, let us look D
( Without warrant that just because satisfying a given condition is enough to ensure an announcement's importance, satisfying that condition is necessary for its important ) = Mistreat the sufficient condition as the necessary condition.
