In my question probability written is 12 and 34
The "probability of 12" and "probability of 34" do not make sense. It must be a typo. Please check for the proper version here: https://gmatclub.com/forum/rashika-is-b ... 25737.html

Critical Reasoning Butler: June 2025
June 11CR 1CR 2

______________________________
CR 1

Ice cream shop owner: Over the past six months, we have surveyed customers about the flavors they enjoy. The results show that our special Chocolate Fudge Chunk was chosen more than any other flavor. In response, we have created a new flavor called Fudge Overload. We believe anyone who enjoys Chocolate Fudge Chunk will enjoy this new flavor. If our belief is correct, then most of our surveyed customers are bound to enjoy Fudge Overload.

Which of the following indicates a flaw in the reasoning above?

(A) The people who responded to the survey may not be representative of the shop's customers overall.

(B) There may be other new flavors that customers would enjoy more than Fudge Overload.

(C) Some customers may have responded that they enjoyed more than just one flavor.

(D) The option most often selected by a group of people may not be selected by most of those people.

(E) To avoid being disappointed, some customers may be unwilling to try new flavors.

______________________________
CR 2

America’s record of protecting species threatened with extinction, which is often depicted as dismal, is in truth an enviable achievement. Since 1973, when the Endangered Species Act took effect, only seven animal species in North America have disappeared. Several hundred others once considered certain to die out continue to exist in the wild. Moreover, a number of species, including the bald eagle and the Arctic peregrine falcon have been or are being taken off the priority-protection list because their numbers have increased considerably now.


(A) The first is a claim that the argument goes on to dispute; the second is information used to strengthen the claim.

(B) The first is a claim that the argument calls into question; the second provides support for the position taken by the argument.

(C) The first is an objection that has been raised against the position taken by the argument; the second is the position taken by the argument.

(D) The first is a claim, the accuracy of which is at issue in the argument; the second is a conclusion drawn on the basis of that claim.

(E) The first is evidence that has been used to support an explanation that the argument challenges; the second is that explanation.
