graywater system
smart water-leak detector
low-flow toilet
high-efficiency washing machine

The correct answer for: Which water-saving technology is aimed at limiting water loss in the home? Is: Graywater system.

Explanation:

To understand this we need to analyze the options carefully.

First of all, we have the smart water-leak detector which is a piece o technology to know if we are leaking water but it doesn't stop it.

Second, we have a low-flow toilet which doesn't limit the water loss of the home but is an improved version of the toilet. So even though it uses less water it doesn't limit the water loss. It just uses less water and you can't reuse it.

Third, A high-efficiency washing machine is the same as the low-flow toilet it's an improved version of a washing machine it doesn't limit just wastes less.

The gray water system, on the other hand, is a system in which you reuse water that was meant to be lost.

i'd say that the moon rock is about 2.2 billion years old.
