Which of the following should be the FOURTH sentence after rearrangement?

The correct option is B.

To find the correct sequence of the paragraph, let us analyze the logical connection between the sentences:

1. First sentence (C): "(C) Paris, a global tourist destination, has recently faced a troubling resurgence of bed bugs across various neighborhoods and popular attractions in the city." - This sentence introduces the central theme and location of the topic (the resurgence of bed bugs in Paris).

2. Second sentence (E): "(E) Experts suggest that international travel and dense urban environments have facilitated the rapid spread of this infestation." - This sentence logically follows C by explaining the causes/reasons for the rapid spread of the infestation introduced in sentence C.

3. Third sentence (D): "(D) This outbreak has raised concerns not only among residents but also tourists, many of whom worry that the pests could travel with them back to their countries." - This sentence discusses the effects and concerns raised by the outbreak described earlier.

4. Fourth sentence (B): "(B) Despite efforts to contain the situation, the bed bugs have infested public transport, popular tourist destinations, and even airports." - This sentence elaborates on how far the situation has escalated despite attempts to handle it, making it the fourth sentence in sequence.

5. Fifth sentence (F): "(F) Furthermore, bed bugs have become a common sight in metros and airports, making control measures even more challenging." - This adds further detail to the widespread presence mentioned in B.

6. Sixth sentence (A): "(A) The government has therefore employed authorities to conduct fumigations, as the situation continues to escalate." - This concludes the paragraph with the ultimate action taken by the government as a response to the escalating situation.

Thus, the correct sequence of sentences is C - E - D - B - F - A.

Therefore, the FOURTH sentence after rearrangement is sentence (B).
