Rewrite each of the following sentences so that related ideas are expressed in similar or parallel structures.

1.)People differ in their fingerprint patterns, in how they talk, and in their dental patterns.

2.)Computers are used to analyze voice patterns, and the patterns can then be compared to those on record.

Should they be

1.) People differ in their fingerprint, voice and dental patterns.

2.) Voice patterns are analyzed by computers, then compared to those on record.

Here's a hint!

In your first sentence, look at these parts of the series:

- in their fingerprint patterns,
- in how they talk, and
- in their dental patterns

Which one of the three is not phrased like the others? How will you fix that?

Yes, both of your revisions are good.

Mine were wrong?

Okay, Thanks (: Sorry didn't see your other comment

You're welcome.

(And, yes, both yours and mine were posted about the same time, huh?)

1.) People differ in their fingerprint patterns, speech patterns, and dental patterns.

In this sentence, we are looking to express related ideas in parallel structures. To achieve this, we can use the same structure for all three items being compared. In this case, we are comparing different patterns.

2.) Computers are used to analyze voice patterns, and to compare them with those on record.

Similarly, in this sentence, we want to parallelize the structure so that both parts of the sentence have a similar format. By adding "to" before "compare" in the second part of the sentence, we make the structure parallel and express the related ideas in a similar way.
