CR 1

A certain watchmaker is attempting to increase its market share by deeply discounting the price of its watches for the upcoming holiday season. The discounts will eat into profits, but because they will be heavily advertised the watchmaker hopes that they will attract buyers away from rival watchmakers' products. In the long term, the watchmaker believes that consumers initially attracted by the discounts may become loyal customers.

In assessing the plan's chances of achieving its aim, it would be most useful to know which of the following?

(A) Whether the watchmaker's competitors are likely to respond by offering deep discounts of their own products

(B) Whether the advertisements will be created by the watchmaker's current advertising agency

(C) Whether some of the watch styles will be more deeply discounted than others

(D) Whether the watchmaker will be able to cut costs sufficiently to maintain profit margins even when the discounts are in effect

(E) Whether an alternative strategy might enable the watchmaker to enhance its profitability while holding a constant or diminishing share of the market

CR 2

Heavy consumption of alcohol causes impaired judgment, a loss of fine motor skills, slower reaction times, a decrease in visual acuity, and other short-term symptoms. Since alcohol can be metabolized in the average person’s body at a rate of 0.015 BAC (or “blood alcohol content”) per hour, a severely intoxicated individual with a BAC of 0.15 should be symptom-free after 10 hours. After this time, if the individual exhibits similar symptoms, such symptoms cannot be caused by alcohol.

Which of the following, if true, most seriously weakens the conclusion above?

(A) Some symptoms normally associated with alcohol consumption may resemble symptoms caused by prescription drugs or even drowsiness.

(B) Increases in BAC are based on the amount of alcohol consumed rather than the number of drinks (some drinks contain more alcohol than others).

(C) Heavy alcohol consumption has numerous long term effects such as cirrhosis of the liver, stomach ulcers, and birth defects.

(D) The metabolic rate of alcohol varies according to a person’s health, weight, diet, and genetic predispositions.

(E) Some people, due to an acute sensitivity to alcohol, cannot even reach a BAC of 0.15 before becoming violently ill.

Parkinson’s Law, an observation advanced by the British civil servant C. Northcote Parkinson, for whom it is named, posits that bureaucracies expand to fill the space available for their expansion. One of Parkinson’s principal pieces of evidence for his Law was the remarkable growth of the British Colonial Office, whose staff continued to swell as the British colonies weakened, and which actually attained its greatest size and influence at the precise moment the British colonial empire collapsed.

Which of the following does NOT illustrate a phenomenon similar to those covered by Parkinson’s Law?

A. The demand for military research tends to correlate positively with the amount of money governments allot to the military each year.

B. The bigger the pie that my aunt bakes, the more of my relatives show up to eat it.

C. Many prominent Hollywood sitcom writers attest that the time it takes to script an episode is dictated by the time a studio provides them to script that episode.

D. Parkinson’s coefficient of inefficiency further predicts that the efficiency of an administrative body decreases in proportion to the number of members added to it.

E. Most professional athletes remark that the amount of money required to sustain their families, image, and lifestyle grows as their income over the course of their careers.

Environmental groups are aggressively protesting the proposed use of a new technique for mining oil from the fringes of underground aquifers. These groups complain that such mining will lead to instances of contaminated groundwater and to sinkholes and other disasters in areas near the proposed mining. But, as the mining companies are quick to retort, the countries already using this technique have not reported any groundwater contamination or environmental issues. Therefore, it is safe to proceed with the new technique.

Which of the following, if true, most undermines the conclusion above?

(A) Some of the countries currently using the new technique have only been doing so for two years or less.

(B) Other widely-used techniques used to procure oil have led to even worse contamination issues than what environmentalists predict could happen with the new technique

(C) The countries currently using the technique are so dependent on oil revenue that they are unlikely to report any problems that might require them to stop.

(D) In the years that the new technique had been in use, several safeguards have been added to prevent the contamination of nearby water.

(E) All of the aquifers near which the proposed technique would be employed are used or will soon be used to provide drinking water for their surrounding communities.

A coffee shop is running a customer raffle in which each slip in a raffle box is labeled either Coffee or Sandwich but not both, indicating the prize on that slip. For one promotional drawing, one slip is selected at random, returned to the box, and then a second slip is selected at random. What is the probability that one selected slip is labeled Coffee and the other is labeled Sandwich?

(1) The probability that the two selected slips have the same label is 5/8.
(2) The number of Sandwich slips in the box is 3 times the number of Coffee slips.

At the beginning of 2023, a fitness club had 800 active members. During 2023, some of the members who had been active at the beginning of the year canceled their memberships and did not rejoin, and every new member who joined during 2023 remained active through the end of the year. If x percent of the members active at the beginning of 2023 canceled their memberships and did not rejoin, and if the number of active members at the end of 2023 was y percent greater than the number active at the beginning of 2023, how many new members joined the club during 2023?

(1) x - y = 7
(2) x + y = 35

Hi, while practicing questions, is it better to stick to official questions only across all levels and sections or its good to practice questions from other popular prep courses also? Because I realised that I am able to do official questions fairly well with good accuracy but my accuracy drops a little when i start practicing questions from other sources. I am not sure why this happens.
Becoz the LOD of questions in OG is not upto the standards
That’s good for beginner to intermediate level but not beyond that

Okay, so you are suggesting that it is better to practice hard medium questions from other popular sources? Like manhattan, e-gmat etc?
If u r struggling with application of concepts then u might also join any GMAT classes to learn shortcuts to save time and strategies to solve even difficult problems quicker

But if you are relying upon self study only then yeah additional practice is required apart from OG
