Q1.
A. is incorrect. Does not express the irony highlighted.
B. is the correct answer. It states that just because male delinquents are accused of committing more serious crimes, they receive more attention. However, female delinquents receive less attention because they commit relatively minor crimes. This irony tries to highlight the biases of the court.
C. Out of scope.
D. Irrelevant. This has nothing to do with the passage.
E. This has been explicitly mentioned in the passage. However, this does not represent the irony of the highlighted lines. This is the answer to a completely different question. Incorrect.
Q2.
A, B, D, and E are not supported by the passage.
C. is the correct answer. The author states in the last line of the passage, "Traditional stereotypes of women as the weaker and more dependent sex have led to earlier intervention and longer periods of misdirected supervision for female delinquents than for males."
Q3.
A. is irrelevant. The author makes no such claim
B. is also irrelevant. Not mentioned in the passage
C. Irrelevant. Neither explicitly mentioned, nor can be inferred from the passage.
D. is correct. This has been clearly mentioned in the beginning of the passage. "an implicit consensus remains among scholars in criminal justice that male adolescents define the delinquency problem in the United States. We suggest two reasons why this view persists. First, female adolescents are accused primarily of victimless crimes, such as truancy, that do not involve clear-cut damage to persons or property. If committed by adults, these actions are not even considered prosecutable; if committed by juvenile males, they have traditionally been looked on leniently by the courts."
E. Out of Scope.
