There is a sentence that is missing in the paragraph below. Look at the paragraph and decide in which blank (option 1, 2, 3, or 4) the following sentence would best fit. Sentence: Having made citizens more and less knowledgeable than their predecessors, the Internet has proved to be both a blessing and a curse. Paragraph: Never before has a population, nearly all of whom has enjoyed at a least a secondary school education, been exposed to so much information, whether in newspapers and magazines or through YouTube, Google, and Facebook. ___(1)___. Yet it is not clear that people today are more knowledgeable than their barely literate predecessors. Contemporary advances in technology offered more serious and inquisitive students access to realms of knowledge previously unimaginable and unavailable. ___(2)___. But such readily available knowledge leads many more students away from serious study, the reading of actual texts, and toward an inability to write effectively and grammatically. ___(3)___. It has let people choose sources that reinforce their opinions rather than encouraging them to question inherited beliefs. ___(4)___.

Correct answer: D
This asks where a missing sentence best fits. The trick is to read the sentence itself and ask what job it does — then find the only gap where that job makes sense.
The sentence to place: "Having made citizens more and less knowledgeable than their predecessors, the Internet has proved to be both a blessing and a curse." This is a balanced, summing-up line — it gathers both the upside (more knowledgeable / blessing) and the downside (less knowledgeable / curse) into one verdict. A summary of both sides can only land after both sides have been laid out.
Walking the gaps:
- Gap 1: only the upside has appeared so far, and the very next line — "Yet it is not clear that people today are more knowledgeable" — would clash with a "both a blessing and a curse" verdict placed here. Too early.
- Gap 2: still only the upside (access to "realms of knowledge"). The downside hasn't arrived yet. Too early.
- Gap 3: a further downside still follows — "It has let people choose sources that reinforce their opinions." A summary here would interrupt before the last negative is even stated.
- Gap 4: now both sides are on the table — the access-to-knowledge upside and both downsides (retreat from serious study, and reinforcing one's own opinions). The balanced verdict caps the paragraph perfectly.
💡 Teacher tip: A sentence that weighs "both a blessing and a curse" is a conclusion. Conclusions go where all the evidence is already in — usually the last gap.
