Yesterday I went down to the market and came away with more than I had intended. The heat lay heavy over everything, and the crowd moved through it wearily. What stayed with me was the smell of the oranges. **Alternatives** The hardest sentence was *Hacía mucho calor y la gente estaba cansada*, where the two clauses are joined by nothing stronger than *y* and the tiredness is left unexplained. 1. "It was very hot, and the people were tired." — the closest rendering, and the flattest. It keeps the parallel structure of the Spanish but loses the sense that one condition produced the other, which the original implies through juxtaposition rather than stating. 2. "The heat was fierce, and it had worn the crowd down." — makes the causal link explicit. Reads more naturally in English, but it commits to a reading the Spanish leaves open, and *fierce* is a degree stronger than *mucho*. 3. "The heat lay heavy over everything, and the crowd moved through it wearily." — chosen. It carries the causal sense through the shared image of the heat as something the crowd is inside, without asserting causation outright, and holds *cansada* at roughly its original strength. Note on *muchas cosas*: rendered as "more than I had intended" rather than "many things". This is the one place the English reaches slightly beyond the Spanish — if you want the plainer sense, "a great many things" stays closer.
