Read each technical excerpt regarding military equipment maintenance and field operations. Match each passage to the statement that expresses its explicitly stated main idea.
- Type I aircraft de-icing fluids are formulated primarily to remove existing ice and snow from aerodynamic surfaces before takeoff. These fluids are applied hot and under high pressure to melt frozen deposits quickly. Because they possess low viscosity, they shear off the aircraft rapidly during takeoff roll, providing minimal ongoing protection against fresh accumulation.Type I de-icing fluids are formulated primarily to melt and clear existing frozen deposits from aircraft surfaces before takeoff.
- White phosphor displays provide operators with superior visual contrast and reduced eye fatigue compared to traditional green phosphor night vision devices. Although green phosphor was historically standard due to peak human eye sensitivity, modern white phosphor technology significantly enhances target discrimination in low-contrast tactical environments during extended night missions.White phosphor night vision devices offer better visual contrast and less eye fatigue than traditional green phosphor units.
- Portable ceramic water filters physically eliminate bacterial pathogens and suspended sediment from untreated field water without requiring chemical additives. As raw water is pumped through the microporous ceramic membrane, microscopic physical barriers block contaminants larger than 0.2 microns, ensuring immediate potable water in austere operational environments.Portable ceramic filters remove bacterial contaminants and sediment from field water through physical barriers without chemical additives.
Cevap
Match the de-icing fluid excerpt to the statement regarding melting and clearing existing ice before takeoff; match the night vision excerpt to the statement regarding improved contrast and reduced eye fatigue; match the water filtration excerpt to the statement regarding physical removal of bacteria and sediment without chemicals.
Each passage features an explicit lead topic sentence that articulates the core function or advantage of the subject. Matching these opening statements to their direct restatements correctly identifies each passage's explicitly stated main idea.
