A.I. Explanation:

Option 1: "Students often find the subject mentioned in the article difficult."

Explanation: The text states that students face difficulty with the engineering mathematics subject due to reasons like lack of preparedness and confidence. This directly supports the conclusion that students find the subject difficult.

Option 2: "The programme described in the paper was successful."

Explanation: While the text mentions that the VSI programme has been successful in similar contexts, it does not provide specific evidence or outcomes to confirm the success of the programme at the University of Western Sydney. Thus, this statement is not supported by the text.

Option 3: "VSI is used to teach people who are studying a subject for the first time."

Explanation: The text specifies that VSI is aimed at students who have previously failed the subject, not those studying it for the first time. Therefore, this option misrepresents the purpose of VSI.

Option 4: "People involved in teaching also took part in this study."

Explanation: The text mentions insights gained by the staff involved in the collaborative learning programme, indicating that those teaching were part of the study. This supports the conclusion that teaching staff participated.

Option 5: "The article describes a technique used for the first time ever."

Explanation: The text does not claim that the VSI technique is being used for the first time; it refers to its success in similar contexts. Therefore, this statement is misleading.

Option 6: "The video recordings were mostly of students doing assessments."

Explanation: The text states that pre-recorded lectures are the main VSI learning tool, but it does not mention that these recordings are primarily of students doing assessments. This option misinterprets the content of the text.
