1. Sentence (C) introduces the central theme and topic of the paragraph: Paris facing a troubling resurgence of bed bugs across neighborhoods and attractions. This serves as the ideal introductory sentence.
2. Sentence (E) follows logically by providing context/reasons from experts as to why this infestation has spread so rapidly (international travel and dense urban environments).
3. Sentence (B) builds on the severity of the infestation, stating that despite efforts to contain it, bed bugs have infested public transport, tourist destinations, and airports.
4. Sentence (F) further elaborates on sentence (B) using the transition word "Furthermore," emphasizing how bed bugs in metros and airports make control measures challenging.
5. Sentence (D) addresses the consequences and concerns raised by this widespread outbreak among both residents and international tourists.
6. Sentence (A) serves as the logical conclusion to the paragraph, stating the action taken in response to the escalating situation: "The government has therefore employed authorities to conduct fumigations, as the situation continues to escalate."

Thus, the complete proper sequence of the paragraph is C - E - B - F - D - A.

Therefore, the LAST sentence after rearrangement is (A).
