Question

5 what is the main idea of the text? a the weather in different parts of the united states can be extremely different on the same day, with weather in the southwestern u.s. being dry and hot and weather in the northeastern u.s. humid and cooler. b some important weather observation tools include thermometers, rain gauges, barometers to measure air pressure, and anemometers that measure the speed of the wind. c meteorologists work with special observation equipment and their own skills of observation to predict patterns in the weather and provide information to people about their local weather predictions.

Explanation:

To find the main idea, we analyze each option:

• Option A describes weather differences in different US regions on the same day, which is a specific example of weather variation, not the main idea of a text likely about meteorology or weather observation.
• Option B lists weather observation tools, which is a detail about how weather is measured, not the main idea.
• Option C explains that meteorologists use special equipment and observation skills to predict weather and provide information, which is a broader statement about the work of meteorologists related to weather (likely the main idea of a text about meteorology/weather observation).

Answer:

C. Meteorologists work with special observation equipment and their own skills of observation to predict patterns in the weather and provide information to people about their local weather predictions.
