Practice Reading: Multiple Choice, Single Answer ID: #4375 Water
Instructions ›
Read the text and answer the multiple-choice question by selecting the correct response. Only one response is correct.
Many homeowners use water butts to collect rainwater falling onto their property. The collected water is most often used for irrigation, thereby reducing the demand for communal water supplies. A lack of data on the microbial content of this run-off water, however, means that it is uncertain whether it may be safely put to other uses. A pilot project is now underway to collect water samples from houses and from other types of buildings. The analysis of these samples may demonstrate that run-off water could be a viable source of drinking water, which would have positive implications for more arid regions that need to develop as many options as possible.

Option 2: "It may be healthy enough to drink."

Explanation: The text indicates that the analysis of water samples may demonstrate that run-off water could be a viable source of drinking water. This aligns directly with the writer's main point, which emphasizes the potential healthiness of run-off water for consumption, especially in arid regions.

Option 1: "It is being tested for microbes."

Explanation: While the text mentions that a pilot project is underway to collect water samples for analysis, the main focus is not on the testing for microbes itself but rather on the potential of run-off water as a viable source of drinking water. This option does not capture the broader implications discussed in the text.

Option 3: "It can be used to irrigate arid regions."

Explanation: Although the text states that collected water is often used for irrigation, it does not specifically claim that run-off water can be used for irrigation in arid regions. This option misrepresents the main point, which is focused on the potential for drinking water rather than irrigation.

Option 4: "It is an alternative to public water supplies."

Explanation: The text discusses the use of collected rainwater to reduce demand for communal water supplies but does not assert that run-off water is a direct alternative to public water supplies. This option lacks the specificity regarding the potential for drinking water, which is the main focus of the text.
