Answer: Option C — Acceleration - The rate of decrease in speed.

One Word Substitutions — Preparation
This question tests your understanding of One Word Substitutions, a key topic in the English Language section. The detailed solution above uses a step-by-step approach to show the reasoning, and where available, a shortcut that helps you solve similar questions in under 90 seconds during the actual exam.
One word substitution questions give a phrase or description and ask for the single word that means the same thing. For example, "a person who cannot read or write" is an "illiterate", and "a speech made without preparation" is "extempore". These questions test vocabulary directly. Words are often grouped by theme: people and their professions or habits (philanthropist, misogynist), fear of things (phobias such as claustrophobia), killing (homicide, regicide), government (democracy, autocracy, oligarchy) and study of subjects (ornithology, entomology). Learning words in these groups, along with common roots such as "-logy" (study of), "-cide" (killing) and "-cracy" (rule), makes them far easier to remember and lets you work out unfamiliar words in the exam. Practise the one word substitution questions below. Each answer includes the word's meaning and root.
