The sentences given in each question, when properly sequenced, from a coherent paragraph. Each sentence is labelled with a letter. choose the most logical order of sentences from among the given choices to construct a coherent paragraph.

(A) In fact, only recently there have been serious studies to find out how many of us actually have nightmares.

(B) now that is changing

(C) the study of nightmares has been curiously neglected

(D) while results so far are inconclusive, it seems fair to say that at least half the population has occasional nightmares.

The correct option is C B A D.

To arrange the given sentences into a coherent and logical paragraph, let us analyze the flow of thought step-by-step:

1. Sentence C ("the study of nightmares has been curiously neglected") serves as an ideal introductory sentence because it introduces the main topic of discussion—the historical lack of research or attention given to the study of nightmares.

2. Sentence B ("now that is changing") directly connects to Sentence C. It highlights a shift in trend, indicating that the traditional neglect mentioned in sentence C is no longer continuing.

3. Sentence A ("In fact, only recently there have been serious studies to find out how many of us actually have nightmares.") expands on the statement in sentence B. It provides concrete proof of how things are changing—by mentioning that serious studies have recently commenced.

4. Sentence D ("while results so far are inconclusive, it seems fair to say that at least half the population has occasional nightmares.") logically concludes the paragraph by sharing the preliminary findings or outcomes of the recent studies mentioned in sentence A.

Thus, the sequence C B A D creates a smooth, logical, and meaningful paragraph.
