<p>This is an <span style="color:#8e44ad;"><strong>Inference Question</strong></span>, as indicated by the word "implies". We have to choose an option that we can reasonably claim to be true, based on the evidence in the passage, specifically about a link between students and the proposed environmental studies programs.</p>
<p><span style="color:#27ae60;"><span style="font-size:20px;">The Right Answer</span></span></p>
<p><span style="color:#27ae60;">D:</span> The passage says that programs "can be marketed to prospective students", and that they can "attract new students or accommodate the interest of existing ones". Furthermore, the passage also states "As the number of students in these skeleton programs grows". We have enough evidence here to say that students are interested in the programs, and will enroll in them.</p>
<p><span style="color:#e74c3c;"><span style="font-size:20px;">The Wrong Answers</span></span></p>
<ul>
<li><span style="color:#e74c3c;">A:</span> This choice has <strong>no evidence</strong>. The proposed program is not compared to existing programs, in terms of student awareness.</li>
<li><span style="color:#e74c3c;">B:</span> This choice has <strong>no evidence</strong>. We have no information regarding students' preferences between a structured curriculum and flexible programs.</li>
<li><span style="color:#e74c3c;">C:</span> This choice has <strong>no evidence</strong>. The passage only claims that the environmental study program can "attract new students", but it doesn't say why they would be attracted.</li>
<li><span style="color:#e74c3c;">E:</span> This choice <strong>contradicts the logic</strong>. The passage states that "as the number of students ... grows" it will lead to "curricular incoherence". The evidence suggests that more students are not enough for the program to be a success. </li>
