What is indicated by the suffix "-meter"?

Instrument for gathering information
Instrument for measuring
A record of analysis
An act of testing

The correct answer is: Instrument for measuring

The suffix "-meter" is commonly used to denote an instrument that measures a specific quantity. This is derived from the Greek word "metron," meaning measure. Instruments that utilize this suffix are designed specifically for quantifying different types of data, such as temperature (thermometer), pressure (barometer), and distance (odometer). Each of these tools serves the primary function of measuring a certain parameter, which is foundational for scientific and technical analysis. In contrast, the other options do not accurately capture the essence of what "-meter" signifies. Options related to gathering information or recording analysis imply broader and more varied functions that do not specifically pertain to measurement. Likewise, while "an act of testing" could arguably involve measurement at times, it does not encapsulate the specific, measuring function that is inherently described by the suffix "-meter." Thus, the correct answer emphasizes the primary purpose of the devices that bear this suffix, which is measurement.
