alfred dottin

Explanation:

The text describes the working conditions during the construction of the Panama Canal. It mentions that diseases (like malaria) were a major issue. The statement "The construction slowed down because diseases spread and killed workers" aligns with the description of the harsh working environment where diseases were prevalent. The other options: workers going on strike for shorter work days is not mentioned in the text about Dottin's experience. The conflict between Panamanians and the US turning violent is also not part of the described experience. Housing being overcrowded is not the main point emphasized in the text which focuses on diseases.

Answer:

The construction slowed down because diseases spread and killed workers.
