Thanks for the kind words. We have several downloadable flashcards. They (and other links) can be found here: http://gmatclub.com/forum/new-resource-every-sentence-correction-concept...

I cant thank you enough for these videos. Your explanations are quite good but, i couldn't answer any question correctly that were given in the Related Content. More over i am taking close to 6 minutes trying to answer questions with more words/text. Do you have any advice for students as me, please.

The strategy for solving this question type is very straightforward. In fact, you'll find that most GMAT resources recommend similar strategies for solving them.

You might want to revisit the lesson on Dissecting Arguments (https://www.gmatprepnow.com/module/gmat-critical-reasoning/video/1133), and just spend some time analyzing CR passages to identify premises and conclusions. Other than that, just keep working at these questions.

Thanks for your advice, I will keep practicing.

Brent, do you recommend that we write the premisses and conclusions (and assumptions) down, even though it costs time? thanks!

Yes, I think it's very useful to have a visual summary of the argument. You can use lots of shorthand and initials to reduce the time it takes.

Businesses are suffering because of a lack of money available for development loans. To help businesses, the government plans to modify the income-tax structure in order to induce individual taxpayers to put a larger portion of their incomes into retirement savings accounts, because as more money is deposited in such accounts, more money becomes available to borrowers.

Which of the following, if true, raises the most serious doubt regarding the effectiveness of the government's plan to increase the amount of money available for development loans for businesses?

(A) When levels of personal retirement savings increase, consumer borrowing always increases correspondingly.

(B) The increased tax revenue the government would receive as a result of business expansion would not offset the loss in revenue from personal income taxes during the first year of the plan.

(C) Even with tax incentives, some people will choose not to increase their levels of retirement savings.

(D) Bankers generally will not continue to lend money to businesses whose prospective earnings are insufficient to meet their loan repayment schedules.

(E) The modified tax structure would give all taxpayers, regardless of their incomes, the same tax savings for a given increase in their retirement savings.

Sir here I chose option c , but A is the correct answer..How?

Mitch explains the problem with answer choice C here: http://www.beatthegmat.com/og-12-cr-q-88-development-loans-t110867.html#...

In this solution, Mitch explains why A is the correct answer: http://www.beatthegmat.com/og12-question-88-reasoning-t81766.html#359782

Let me know if you'd like me to add to the discussion

Guidebook writer: I have visited hotels throughout the country and have noticed that in those built before 1930 the quality of the original carpentry work is generally superior to that in hotels built afterward. Clearly carpenters working on hotels before 1930 typically worked with more skill, care, and effort than carpenters who have worked on hotels built subsequently.

Which of the following, if true, most seriously weakens the guidebook writer’s argument?

(A) The quality of original carpentry in hotels is generally far superior to the quality of original carpentry in other structures, such as houses and stores.
(B) Hotels built since 1930 can generally accommodate more guests than those built before 1930.
(C) The materials available to carpenters working before 1930 were not significantly different in quality from the materials available to carpenters working after 1930.
(D) The better the quality of original carpentry in a building, the less likely that building is to fall into disuse and be demolished.
(E) The average length of apprenticeship for carpenters has declined significantly since 1930.

Sir actually the correct ans is B I think , but many members in GMAT CLUB gave C,D Etc

There are tons of great comments on the following Beat The GMAT thread, but my favorite is the one here: http://www.beatthegmat.com/guidebook-writer-t40639-15.html#763347

Also, Mitch has a great response here: http://www.beatthegmat.com/og-question-t284714.html#751549

Let me know if you'd like me to add to the discussion

UCLA Sociologist: Between 1962 and 2012, the marriage rate (that is the percentage of adult women over 16 who get married for the first time each year) fell from 110 marriages a year per 1,000 unmarried women to just 37, a stunning 66 percent decline. Given this trend, there will likely be no women getting married for the first time by 2050!

Which of the following, if true, exposes a flaw in the sociologist’s reasoning?

A) The average age of marriage has increased dramatically in the past 20 years.
B) Today’s divorce rates are expected to rise dramatically over the next 40 years.
C) More women are expected to get married for a second and third time in the next 40 years.
D) Many women are deciding to simply live with their partners rather than get married.
E) Marriage is much less likely to occur today for the first time than it was in the 1960’s.
Sir this is a statistical argument question Sir it took me nearly seven mins to solve correctly,how to manage the time efficiently. Ans A

On test day, you need to manage your time effectively. After 2-3 minutes, you need to pick an answer choice and move on.

By the way, Mitch provides a great explanation here: http://www.beatthegmat.com/critical-reasoning-veritas-prep-qn-doubt-t282...

Brent, could you help me on this below question? It is a little bit confuse for me, and in the GMAT Club Forum there are people who choiced C, D and E. I choiced the letter E.

In the United States, of the people who moved from one state to another when they retired, the percentage who retired to Florida has decreased by three percentage points over the past ten years. Since many local businesses in Florida cater to retirees, these declines are likely to have a noticeably negative economic effect on these businesses and therefore on the economy of Florida.

Which of the following, if true, most seriously weakens the argument given?

(A) People who moved from one state to another when they retired moved a greater distance, on average, last year than such people did ten years ago.

(B) People were more likely to retire to North Carolina from another state last year than people were ten years ago.

(C) The number of people who moved from one state to another when they retired has increased significantly over the past ten years.

(D) The number of people who left Florida when they retired to live in another state was greater last year than it was ten years ago.

(E) Florida attracts more people who move from one state to another when they retire than does any other state.

Thanks!

Brent,

I have another doubt. The below question I am confused between the answer A and the answer C. In the GMAT Forum some people choiced A, while others choiced C. Could you help me please?

Brent, why this below question is not the answer B? Could you explain me please?

Hi Brent,

I am struggling a bit with weaken the arguments questions, particularly 650+ difficulty level. I am planning to go through this video again, do you want to suggest anything else to improve this?

Weaken the Arguments questions can get pretty tricky. Be sure to take the time to fully grasp the conclusion of the argument before you begin checking the answer choices.

Hi Brent,

I was confused between D and E, and chose D. Can you explain me why D is wrong.

https://gmatclub.com/forum/the-introduction-of-new-drugs-into-the-market-is-frequently-220355.html

Question link: https://gmatclub.com/forum/the-introduction-of-new-drugs-into-the-market...

PREMISE: shortage of human subjects prevents new drugs on market

PREMISE: lives/health of FUTURE generations depend on treatments that are currently experimental

CONCLUSION: physicians morally wrong when, in absence of existing treatment, fail to encourage patients to volunteer for trials.

Answer choice D says "An experimental drug cannot legally be made available to patients unless those patients are subjects in clinical trials of the drug"

How does this weaken the conclusion that physicians are morally wrong when the don't encourage patients to volunteer for trials?

If anything it strengthens the argument, because it suggests that doctors SHOULD encourage their patients to participate in the trials to get the drugs.

Conversely, answer choice E says "Physicians have an overriding moral and legal duty to care for the health and safety of their current patients."

That is, doctors are NOT obliged to ensure the health of FUTURE patients (future patients who will benefit from the tested drugs). Instead, the doctors are obliged to ensure the health of their PRESENT patients, and if there are potential dangers involved in these clinical trials, then the doctor should NOT encourage his/her patient(s) to participate.

Hi Brent-

Please help with below question, I selected ans. choice B.

Also please confirm is it weaken or strengthen the argument question?

Question link: https://gmatclub.com/forum/editorial-the-roof-of-northtown-council-s-equ...

This is actually a Strengthen the Argument question. I placed it in the wrong place. I've now moved it to correct location.

Incidentally, here's my solution: https://gmatclub.com/forum/editorial-the-roof-of-northtown-council-s-equ...

ASIDE: If this were actually a Weaken the Argument question (since I did have it in a long list of Weaken the Argument questions), then B would have been the best answer (as you have chosen).

Hi Brent- is it sufficient if we only focus on Reinforcement activities given at the end of each CR lesson and Practice Questions from Various Official Guides given at the end of SC module?
gmat-admin's picture

Yes, that should be a sufficient amount of practice.
