Concept:To strengthen the report of gender bias, a statement must directly show discrimination against women in admissions.
Explanation:Statement I says technical courses offer more seats to men than women.
This indicates possible bias, but it only relates to seat distribution in one area.
Statement II talks about varying technical skills, which is about course requirements, not gender discrimination.
It does not strengthen the report.
Statement III mentions more seats allotted to women last year.
Since allotment happens after admission, it does not prove bias in the admission process itself.
It weakens or is irrelevant.
Statement IV says many courses allow only men to enroll.
This is clear and direct gender discrimination at the admission stage, so it strongly strengthens the report.
Statement V mentions absence of female faculty.
Faculty hiring is not part of student admission, so it does not support the report.
Among the statements, IV gives the clearest evidence of gender bias in the admission process.
Therefore, the statement that strengthens the report is Only IV.
Answer:D. Only IV
