Step	Type	Explanation	Answer
1	Problem	Find the prefix for the word "Precollide" ?
2	Clue	A prefix is a letter or group of letters, for example 'un-' or 'multi-', which is added to the beginning of a word in order to form a different word.

5	Choice.B	Choice B is correct. The word "pre" means "before," so when we add it to "collide," it becomes "pre-collide," which means "to collide before something else happens." So, the prefix "pre" fits perfectly, showing that something is happening before a collision.	pre
6	Choice.C	Choice C is incorrect because the prefix for the word "Precollide" is actually "pre-," not "preco." Prefixes are added to the beginning of words to change their meaning, and in this case, "pre-" means "before." So, the word should be written as "precollide."	preco

Problem

Find the prefix for the word "Precollide" ?

Clue

A prefix is a letter or group of letters, for example 'un-' or 'multi-', which is added to the beginning of a word in order to form a different word.

Sumup

Can you summarize what you’ve understood in the above steps?

Choice.A

Choice A is incorrect. The prefix "pre-" means before, but "p" alone doesn’t make sense. "Pre-" comes before a word to change its meaning. For "precollide," the correct prefix is "pre-," not just "p." So, it’s "precollide," not "pcollide."

Choice.B

Choice B is correct. The word "pre" means "before," so when we add it to "collide," it becomes "pre-collide," which means "to collide before something else happens." So, the prefix "pre" fits perfectly, showing that something is happening before a collision.

pre

Choice.C

Choice C is incorrect because the prefix for the word "Precollide" is actually "pre-," not "preco." Prefixes are added to the beginning of words to change their meaning, and in this case, "pre-" means "before." So, the word should be written as "precollide."

preco

Choice.D

Choice D is incorrect. The prefix for "Precollide" is not "pr." The correct prefix is "pre-," which means "before." So, the correct form of the word is "precollide," where "pre-" comes before "collide."
