Final answer:
Sentence 1 is in the wrong place as it breaks the cohesiveness of the passage that primarily focuses on describing Guatemala City and its challenges.
Step-by-step explanation:
The sentence in the passage that is in the wrong place is sentence 1, which mentions heavy rains leading to a mudslide in 2005. The rest of the sentences in the passage are focused on describing Guatemala City, its status as the capital and largest city in Central America, its population, and the kinds of natural disasters it has faced, like earthquakes. Sentence 1 disrupts the cohesiveness of these pieces of information and therefore seems out of context with the main topic of the paragraph, which is Guatemala City.
