Hi.. can someone plz help me with these questions?

Technological improvements and reduced equipment costs have made converting solar energy directly into electricity far more cost-efficient in the last decade. However, the threshold of economic viability for solar power (that is, the price per barrel to which oil would have to rise in order for new solar power plants to be more economical than new oil-fired power plants) is unchanged at thirty-five dollars.

Which of the following, if true, does most to help explain why the increased cost-efficiency of solar power has not decreased its threshold of economic viability?
(A) The cost of oil has fallen dramatically.
(B) The reduction in the cost of solar-power equipment has occurred despite increased raw material costs for that equipment.
(C) Technological changes have increased the efficiency of oil-fired power plants.
(D) Most electricity is generated by coal-fired or nuclear, rather than oil-fired, power plants.
(E) When the price of oil increases, reserves of oil not previously worth exploiting become economically viable.
----------------------------------------------------------------
Products sold under a certain brand name used to command premium prices because, in general they were superior to nonbrand rival products. Technical expertise in product development has become so widespread, however, that special quality advantages are very hard to obtain these days and even harder to maintain. As a consequence, brand name products generally neither offer high quality nor sell at higher prices. Paradoxically, brand names are a bigger marketing advantage than ever.

Which of the following, if true most helps to resolve the paradox above?
(A) Brand names are taken by consumers as a guarantee of getting a product as good as the best rival products.
(B) Consumers recognize that the quality of products sold under invariant brand names can drift over time.
(C) In many acquisitions of one corporation by another, the acquiring corporation is interested more in acquiring the right to use certain brand names than in acquiring existing production facilities.
(D) In the days when special quality advantages were easier to obtain than they are now, it was also easier to get new brand names established.
(E) The advertising of a company's brand-name products is at times transferred to a new advertising agency, especially when sales are declining.

Q1) E as it suggests why oil powered plants are still considered to be economically viable even though technology has made the solar power plant more cost effective.
Q2) A

Are these the OAs arch?

thanks

the OAs are C & A respectively... how did u arrive at ur answer for the 2nd question?

ashish y did u rule out option E in Q1
ashishjha100 Says
My picks are C & A..........wat r the OAs?

There is a paradox in that brand names are still considered in high esteem even though technology has made special quality advantages very hard to come by.
A sorts this paradiox by saying tht consumers take branded products as a guarantee for good quality.
B - The passage does not say anythingabout non-branded/invariant branded products.
C - Irelevant
D- Out of scope
E - Irrelevant

Hope thishelps.

Thanks

Q1) Ans:E ...It seems appropriate...what does junta think?

1. Threshold at which solar power plants will become more economical than oil-fired plant is stable at $35/barrel. This means the price of oil is not rising above $35/barrel. At the same time, cost of running solar power plant has came down, then what's the reason that the threshold is stable ?
All other options are irrelevant except A and C.
A - Oil prices have fallen. Although it could be a possible reason but such a direct relation is generally not the answer.
C - Technological changes have increased the efficiency of oil-fired power plants and this factor keeps balancing the threshold which could have fallen otherwise due to the increasing cost - efficiency of solar power plants.

@shrikant and jamiafahad
E - Question has never said/implied that oil prices have increased/can increase, hence new options for oil have to be chosen. So, this option should not be considerd. Don't go too far from the range of the question.

Answer should be C.

2.Special quality advatages are very hard to obtain these days and even harder to maintain. Then why brand names have a bigger marketing advantages ?
Only A and B are practical options -
B - Question didn't mention anything about invariant/persistent brand. It only talks about Branded vs Non-branded products.
A - This option has become really strong as it says the word "guarantee". Consumers take the branded product as a guarantee that they are as good as rival products if not superior.
Answer should be A.
Hope it explains.

Hi Guys! I could not answer the folowing CR in 2 minutes nor I could get the right answer. Pls. help with properly explanation.

F: We ought not to test the safety of new drugs on sentient animals, such as dogs and rabbits. Our benefit means their pain, and they are equal to us in the capacity to feel pain.
G: We must carry out such tests; otherwise, we would irresponsibly sacrifice the human lives that could have been saved by the drugs.
Which of the following, if true, is the best objection that could be made from Fs point of view to counter Gs point?
(A) Even though it is not necessary for people to use cosmetics, cosmetics are also being tested on sentient animals.
(B) Medical science already has at its disposal a great number of drugs and other treatments for serious illnesses.
(C) It is not possible to obtain scientifically adequate results by testing drugs in the test tube, without making tests on living tissue.
(D) Some of the drugs to be tested would save human beings from great pain.
(E) Many tests now performed on sentient animals can be performed equally well on fertilized chicken eggs that are at a very early stage of development.

@ paki,
First of all, no options seem to be a direct/obvious answer. I feel that there is no option which is directly supporting F's point and contradicting G's point of view.
Hence, I am going for option A as it says even though it's not necessary to use cosmetics, cosmetics are also being tested on sentient animals. This point supports F's view and counteract G's view as cosmetics are not-so-important for human lives even then its being first tested on animals.

What's the OA ?

I'll go wid E...tell me if im right!

OA is E according to 1 0 0 0 c r
But pls. someone who can explain in detail? many tks

A: This statement looks more on the lines of G countering F..
B:Though, this to some extent counters what G says,it looks more abstract in nature.
C:This looks like a stmt. being made by F to substantiate whatever he's said before..So can't be a counter statement.
D:Ive made nothing out of it..or in other words, I did not find it to be an appropriate counter statement.
E:This, to a large extent satisfies coz F is pointing out that the tests performed on fertilized eggs produce similar results as wid done wid animals..SO this offers an alternative..

In order to relieve congestion in the airspace near the airports of a certain country, transportation officials propose sending passengers by new rapid trains between the countrys major airport and several small cities within a 300-mile radius of it. This plan was proposed even though the officials realized that it is the major airport that is congested, not those in the small cities.
The plan to relieve congestion would work best if which of the following were true about the major airport?
(A) Rail tickets between the airport and the small cities will most likely cost more than the current air tickets for those routes.
(B) Most passengers who frequently use the airport prefer to reach their cities of destination exclusively by air, even if they must change planes twice.
(C) There are feasible changes in the airports traffic control system which would significantly relieve congestion.
(D) Some of the congestion the airport experiences could be relieved if more flights were scheduled at night and at other off-peak hours.
(E) A significant proportion of the airports traffic consists of passengers transferring between international flights and flights to the small cities.
Questions 10-11 are based on the following.
An annually conducted, nationwide survey shows a continuing marked decline in the use of illegal drugs by high school seniors over the last three years.
10. Which of the following, if true, casts most doubt on the relevance of the survey results described above for drawing conclusions about illegal drug use in the teen-age population as a whole?
(A) Because of cuts in funding, no survey of illegal drug use by high school seniors will be conducted next year.
(B) The decline uncovered in the survey has occurred despite the decreasing cost of illegal drugs.
(C) Illegal drug use by teen-agers is highest in those areas of the country where teen-agers are least likely to stay in high school for their senior year.
(D) Survey participants are more likely now than they were three years ago to describe as heroic people who were addicted to illegal drugs and have been able to quit.
(E) The proportion of high school seniors who say that they strongly disapprove of illegal drug use has declined over the last three years.
11. Which of the following, if true, would provide most support for concluding from the survey results described above that the use of illegal drugs by people below the age of 20 is declining?
(A) Changes in the level of drug use by high school seniors are seldom matched by changes in the level of drug use by other people below the age of 20.
(B) In the past, high school seniors were consistently the population group most likely to use illegal drugs and most likely to use them heavily.
(C) The percentage of high school seniors who use illegal drugs is consistently very similar to the percentage of all people below the age of 20 who use illegal drugs.
(D) The decline revealed by the surveys is the result of drug education programs specifically targeted at those below the age of 20.
(E) The number of those surveyed who admit to having sold illegal drugs has declined even faster than has the number who have used drugs.

Pls. post answers with explanations!, Tks in advance!

@paki

Here are my answers and explanations -

1. The plan to relieve congestion at major airport would work best if which of the following were true about the major airport?

A - Rail tickets between the airport and the small cities will most likely cost more than the current air tickets for those routes. But the statement didn't said that new rapid trains will be cheaper comparatively. Insufficient information.
B - Most passengers who frequently use the airport prefer to reach their cities of destination exclusively by air, even if they must change planes twice. Hold it.
E - A significant proportion of the airports traffic consists of passengers transferring between international flights and flights to the small cities. This option justifies the reason of congestion around major airport and how can it be resolved by launching rapid trains between major airport and small cities. This option is better than B.

Answer should be E.

2. Which option weakens the conclusion about illegal drug use in the teen-age population as a whole ?

C - Illegal drug use by teenagers is highest in those areas of the country where teen-agers are least likely to stay in high school for their senior year. And the survey talks only about decline in the use of illegal drugs by high school seniors. So, most of the teenagers dont come under the category of high-school seniors, so this statement weaks the conculsion.

Answer should be C.

3. Which option strenghtens the conclusion made by survey that that the use of illegal drugs by people below the age of 20 is declining ?

C - The percentage of high school seniors who use illegal drugs is consistently very similar to the percentage of all people below the age of 20 who use illegal drugs. As the percentage of high school seniors taking drugs is consistently similar to people below 20 (i.e teenagers) who take drugs.So, the survey's conclusion is also true about teenagers.

Answer should be C.

What are the OAs ?

OA = your answers, congrats dude!

For question (2).. What about option (E)? I must be missing something if i thought it helped to weaken the conclusion.. can you please point out my mistake? Thanks!
