When preparing food, it is especially important to keep the temperature out of the danger zone because bacteria can grow rapidly in this temperature range.
Bacteria grow at very high speeds in the range of the danger zone, which is the range of temperatures between 40° F and 140° F. Leaving food out at room temperature for a long time (more than 1-2 hours) can lead to some bacteria to grow to levels which are dangerous.
Hope this helps:)

Answer: The right answer is Cave-ins.
Explanation: Excavations and trenches are basically the man-made cuts inside the Earth's surface. These are made for multiple purposes such as mining or tunneling. One of the obvious risk while working in such excavations and trenches is cave-ins. It is basically collapse of that excavation or Trench. The roof of the mine collapses and people working under it get buried inside those excavations in trenches.
