The Water Cycle
Water is needed to sustain practically all life functions on planet Earth. A single drop of this compound is composed of an oxygen atom that shares its electrons with each of the two hydrogen atoms.
The cycle starts when precipitation, such as rain, snow, sleet, or hail, descends from the sky onto the ground. Water that is not absorbed immediately from the precipitation is known as runoff. The runoff flows across the land and collects in groundwater reservoirs, rivers, streams, and oceans.
Evaporation takes place when liquid water changes into water vapor, which is a gas. Water vapor returns to the air from surface water and plants.
Ultimately, condensation happens when this water vapor cools and changes back into droplets of liquid. In fact, the puffy, cotton clouds that we observe are formed by condensation. When the clouds become heavily laden with liquid droplets, precipitation ensues.

Which transitional expression best replaces 'ultimately' in the following sentence: 'Ultimately, condensation happens when water vapor cools'?

  • A. While
  • B. Furthermore
  • C. Since
  • D. Moreover
Correct Answer: A

Rationale: The word 'ultimately' is used to indicate the final step in a process. 'While' can serve as a transition that suggests a time-based connection, which works well in the context of the water cycle's progression. The other options, such as 'furthermore' and 'moreover,' are used to add information, and 'since' indicates causality, none of which is appropriate in this context.
