- You can omit words or even whole clauses if there is no ambiguity: e.g., “I walk as fast now as [I WALKED] when I was younger.”

Example 2 (with restrictive modifier):

Compare similar verbs:

Like, such as, including
“Like” is strictly a comparison word on the GMAT and cannot be used to introduce examples. For introducing examples, use “such as” and “including.”
- Correct: The country could get its economy back on track via the use of such approaches as improving the quality of the educational system, revamping bureaucracies, and negotiation of better trade deals.
Like vs. As
“Like” can be used only as a preposition. Prepositions always take an object, and the object of a preposition is always a noun or pronoun. Can’t use “like” to connect clauses. In comparison between two clauses, “as” must be used.
- Incorrect: The teacher acts like she were a drill sergeant.
- Correct #1: The teacher acts as though she were a drill sergeant.
- Correct #2: The teacher acts like a drill sergeant.
As Opposed To vs. Unlike
“As opposed to” doesn’t mean “unlike.” The meaning of “as opposed to” is along the lines of “rather than” or “not.”
Few vs. Less
Few → countable nouns
Less → uncountable nouns
- Incorrect: Although Jeffrey finds the dishes bland, he cooks with less salt, pepper, and spices than normal when he prepares dinner for his kids, who are picky eaters.

Number vs. Amount
Number → countable noun
Amount → uncountable noun
Quantities of Time, Money, or Weight
Unless the units themselves are being counted, time, money, and weight are treated as uncountable nouns similar to water.
- About the units themselves: How many minutes are left? Many Euros have been spent.
- Not about the units themselves: The tank currently contains less than 2 gallons of water.
Example:
- Incorrect: Aware that they didn’t have many more than 2 hours to finish setting up, the stage crew decided to postpone the sound check.
- Correct: Aware that they didn’t have much more than 2 hours to finish setting up, the stage crew decided to postpone the sound check.
Greater than vs. More than
- “Greater than” = “larger than” or “higher than”
→ Compares the levels, sizes, degrees, magnitudes, or extents of things - “More than” ≠ “larger than” or “higher than”
→ “More than” is a determiner that modifies what follows it
e. g., Greater than: The amount of money misdirected to the bank’s small branch in Florida was much greater than the amount that that branch could put to work.
e. g., More than: Sara has more space than Olivia has.
Greater than vs. More than: Statistics
When statistics are compared, use “greater than” instead of “more than.”
e.g., The standard deviation of the test scores of the students in group A was greater than that of the test scores of the students in group B.
