Difficulty: EasyExplicit Main Idea

Passage:
Tactical Water Purification Systems (TWPS) are essential for sustaining deployed military units in austere environments by producing potable drinking water from contaminated local sources. Equipped with microfiltration membranes and high-pressure reverse osmosis units, these mobile systems can filter up to 1,500 gallons of water per hour. They effectively remove chemical agents, biological pathogens, suspended sediments, and dissolved salts from fresh, brackish, or seawater sources. By providing a reliable on-site water supply, tactical purification units reduce the logistical burden and danger of transporting bottled water across hostile territory.

Statement: According to the passage, Tactical Water Purification Systems (TWPS) primarily serve to sustain deployed units by transforming contaminated local water sources into safe drinking water.

Answer: Answer

Answer

True
The statement is true because the passage explicitly states in the lead sentence that the primary role of Tactical Water Purification Systems (TWPS) is to sustain deployed units in austere environments by generating potable drinking water from local contaminated sources.
