Question

Choose the word that means “to make happen at the same time.”

Weather is unpredictable and measurable. We can use tools to collect weather data, but we never know exactly what will happen. For example, a barometer is an instrument that measures air pressure. This measurement provides information about how the weather will be changing. Meteorologists use this and other data to synchronize their forecasts to the changing conditions.
