Direction for Questions 24 and 25: Read the following sets of four sentences and arrange them in the most logical sequence to form a meaningful and coherent paragraph. I. Doubts Linger about Face book's ability to be a business. Financial markets had also cratered since the Microsoft deal. II. Big, as that is, it's considerably less than the $15 billion valuation that Microsoft and Li Ka-shing accepted in October 2007. III. Milner's confidence that Facebook will eventually be profitable at a gigantic scale is what emboldened him to invest initially at a price that valued the company at $10 billion. IV. But Milner's enthusiasm is such that not only did he buy stock from Facebook, he will also be spending as much as $300 million more buying stock from employees and outside investors

Sentence $III$ is the best opening because it introduces Milner, his confidence, and the initial investment context. Sentence $IV$ follows naturally because it begins with “But Milner's enthusiasm is such that...”, continuing the idea of his confidence and adding further investment details. Sentence $II$ must come after $III$ or $IV$ because “Big, as that is” refers to the valuation just mentioned earlier. After the $10$ billion valuation is introduced, $II$ compares it with the earlier $15$ billion valuation. Sentence $I$ works best at the end because it explains why the later valuation was lower: doubts about Facebook's business model and the crash in financial markets since the Microsoft deal. So the coherent order is $III, IV, II, I$. Rechecking the options, this matches option $D$.
