Question 45: It is (A) essential to provide high school students with adequate career (B) orientation, so they can make more (C) informative decisions about their future (D) major.

AI-attributed reasoning (no explanation printed in the source; answer key on page 4 gives 45.B): The source answer key lists 45.B. Note, however, that standard usage points to (C): 'informative decisions' should be 'informed decisions' (an 'informed decision' = a decision made with good knowledge), while 'career orientation' and 'future major' are correct. The official key 45.B is preserved as printed; this apparent key/analysis discrepancy is flagged rather than silently corrected.
