What was a requirement for admission to a state university in Texas from the 1950s to the 1970s?

The correct answer highlights that during the period from the 1950s to the 1970s, admission to a state university in Texas was contingent on meeting specific criteria that underscored the importance of academic achievement. In addition to possessing a Texas high school diploma, students were required to achieve high grades and compete well on standardized tests like the SAT. This combination ensured that admitted students had not only completed the necessary secondary education prerequisites but also demonstrated the academic ability needed for success in higher education.

At that time, Texas universities emphasized both academic records and standardized testing to create a selective admissions process that aimed to maintain educational quality. High grades reflected a student's capacity to handle college-level coursework, while competitive SAT scores provided a uniform measure of academic preparedness.

The other potential answers lack the comprehensive combination of these admissions criteria, highlighting why those options do not capture the full requirements as effectively as the correct choice does.
