During the 3 months before and the 3 months after major earthquake in California, students at a college there happened to be keeping a record of their dreams. After experiencing the earthquake, half of the students reported dreaming about earthquakes. During the same 6 months, a group fo college students in Ontario who had never experienced an earthquake also recorded their dreams. Almost none of the students in Ontario reported dreaming about earthquakes. So it is clear that experiencing an earthquake can cause people to dream about earthquake.
Which one of the following, if true, most strengthens the argument?
(A) Before the California earthquake, no more of the students in California than of those in Ontario recorded dreams about earthquakes.
(B) The students in California where members of a class studying dreams and dream recollection, but the students in Ontario were not.
(C) Before they started keeping records of their dreams, many of the students in Cal. had experienced at least one earthquake.
(D) The students in Ontario reported having more dreams overall, per student, than students in Cal. did
(E) The students in Ontario who reported having dreams about earthquakes recorded the dreams as having occurred after the California earthquake.


During the 1980s the homicide rate in Britain rose by 50 percent. The weapon used usually was a knife. Potentially lethal knives arc sold openly and legally in many shops. Most homicide deaths occur as a result of unpremeditated assaults within the family. Even if these are increasing, they would probably not result in deaths if it were not for the prevalence of such knives. Thus the blame lies with the permissiveness of the government that allows such lethal weapons to be sold.

  Which one of the following is the strongest criticism of the argument above?

(A) There are other means besides knives, such as guns or poison ,that can be used to accomplish homicide by a person who intends to cause the death of another.

(B) It is impossible to know how many unpremeditated assaults occur within the family, since many are not reported to the authorities.

(C) Knives are used in other homicides besides those that result from unpremeditated assaults within the family.

(D) The argument assumes without justification that the knives used to commit homicide are generally purchased as part of a deliberate plan to commit murder or to inflict grievous harm on a family member.

(E) If the potentially lethal knives referred to are ordinary household knives, such knives were common before the rise in the homicide rate; but if they are weaponry, such knives are not generally available in households.

In this type of questions we have to ensure that the groups being compared are the same. In this case, students in California and students in Ontario are similar interms of their dreaming about earth quakes. A provides us that.

If the students in California naturally dream more times about earth quakes than students in Ontario, then the evidence of 6 months would not be enough to support the conclusion.

E says that so called lethal knives as mentioned in the argument are nothing but kitchen knives. And no lethal knives are so prevalent. E is weaking the argument. No?

C and E

The conclusion of the 1st argument is its last line -

"So it is clear that experiencing an earthquake can cause people to dream about earthquake"

The only choice that directly bolsters the conclusion is choice C.

For me: A and D

First see the beginning of the argument. It considers 6-monthly period. Not only 3 months after the earthquake, but also 3 months before the earthquake. But then, the author of the argument developes it comparing behavior of two groups of students only after experiencing the earthquake. So in order to strengthen the argument the answer choice must include some information about the students' dreams before the earthquake. We need a comparison here. The argument would not make sense if the students in Cal. had dreams about earthquake also before the earthquake.
(A) Before the California earthquake, no more of the students in California than of those in Ontario recorded dreams about earthquakes.
Correct! Shows the comparison we need
(B) The students in California where members of a class studying dreams and dream recollection, but the students in Ontario were not.
not relevant
(C) Before they started keeping records of their dreams, many of the students in Cal. had experienced at least one earthquake.
the period is not relevant
(D) The students in Ontario reported having more dreams overall, per student, than students in Cal. did
not relevant
(E) The students in Ontario who reported having dreams about earthquakes recorded the dreams as having occurred after the California earthquake.
weakens the argument as offers another theory of such dreams


The second is D for me.

Please provide the OA :)

B is no way.
The argument is that the government is guilty for increasing crimes.
The quantity of unpremeditated assaults doesn't play any role. Even if we do not know how many assaults exactly there were.. who cares?

E is a slightly more complex argument which makes it the right answer.

In the passage it is mentioned that the murders are not premeditated. If the murder is not premeditated it would most likely (almost always) be carried out using a common item which can be found spontaneously in the household. Therefore the knives in question will be the ones that household members can find spontaneously. 99 percent of the time this will be a kitchen knife. Therefore kitchen knives caused the increase in the rate of homicide. These items have been around for a very long time, therefore it weakens the case that the government is to blame

D claims that unpremeditated murders are actually premeditated.
