OFFICIAL EXPLANATION


The overall tone expressed by the first sentence of the text suggests that Elton's performance in the previous semester was not very exciting. The word 'nothing' which precedes blank1 suggests that 'write home about' fits in the blank as it completes the idiom 'nothing to write home about' (of little value or importance). The missing word in blank 2 should explain Elton's decision in order to get good grades in the current semester. The words 'write elaborate notes' and 'pay heed to the minor details' in the second sentence suggest that 'work assiduously' aptly fits in blank 2. From the last sentence of the text, it is clear that 'paying heed to minor details' is in sharp contrast to Elton's previous habit of the 'big- picture approach'. Thus, 'scant respect' which suggests his attitude towards minor details best fits in blank 3 . Thus, the answer is $\mathrm{B}, \mathrm{E}, \mathrm{G}$.
