Explicación
## Step 1The problem is asking us to identify the type of dam that is considered the most dangerous and has been referred to as the "drowning machine". The options provided are "large-structure", "low-head", and "high-head". ## Step 2The term "drowning machine" is often used to describe a "low-head" dam. This is because low-head dams can create dangerous conditions such as standing waves, hydraulic jumps, and recirculating eddies, which can trap and drown swimmers and even experienced divers.## Step 3The term "low-head" refers to the height of the dam, which is typically less than 4 meters. This is in contrast to high-head dams, which are over 15 meters high.## Step 4The term "large-structure" is a general term that can apply to any type of dam, regardless of its height or danger level. Therefore, it does not specifically refer to the most dangerous type of dam.
