Criticism Arises Over 'Error' in Question 20 of the CSAT Life Science II Exam

Objection Submission for Questions Until the 22nd, Results Announcement on the 29th

[Asia Economy Reporter Han Jinju] There has been a claim that there is an error in question 20 of the Life Science II subject in the science inquiry section of the 2022 College Scholastic Ability Test (CSAT) held on the 18th.

On the CSAT question and objection bulletin board on the 21st, more than 20 posts raising objections to question 20 of Life Science II were uploaded.

The question consists of a prompt and answer choices. Assuming group I is the Mendel group in the prompt, the last condition "the frequency of B is greater than the frequency of B* in both I and II" is not met, so the assumption is rejected. Therefore, group II must be the Mendel group.

Calculating the number of individuals in group I based on this leads to a negative number of individuals with the genotype B*B*, which is also contradictory. Ultimately, it is pointed out that the problem's setup itself is incorrect.

Kim Yeonseop, head of the science team at Jongno Academy, explained, "There is a contradiction in the prompt of question 20 in Life Science II, so the problem is invalid," and added, "Since no group satisfies all the given conditions, question 20 is erroneous."

The number of applicants for Life Science II was 7,868, accounting for 1.6% of the total number of applicants in the science inquiry section. The CSAT objection submission deadline is until 6 p.m. on the 22nd, and the review results will be announced on the 29th.
