EN4 Word Choice & Concision

On the English section, four choices will often say the same thing at four different lengths. When that happens the ACT wants the shortest one that keeps every piece of information and is still idiomatic English. That is not a stylistic preference the test hides from you - it is the single most predictable pattern in the section, and it decides a large share of the Knowledge of Language questions.

The default: among choices that mean the same thing, pick the shortest. The two exceptions: when the short choice drops information the sentence needs, and when the short choice is not idiomatic English.

Exception 1: brevity that costs information

Shortest wins only among choices that are equally complete. If cutting words also cuts a fact, a contrast, or the thing being compared, the longer choice is right.

The wingspan of a golden eagle is greater than ______ a red-tailed hawk.
a is shorter than that of, but it compares a wingspan to a bird. That of stands in for the wingspan of, so the sentence compares like with like. The extra two words are carrying meaning, so they stay.

Exception 2: brevity that breaks the idiom

Phrasal verbs need their particles. Put off a decision means postpone it; put a decision means nothing. Prepositions that follow particular verbs and adjectives - capable of, different from, interested in - are not padding either. Cut the words that repeat; never cut the words that fix the meaning.

Redundancy: two words for one idea

The most common version is a modifier that restates the definition of the word it modifies. To eliminate something is already to remove all of it, so completely eliminate says completely twice. Learn the pairs the test reuses:

basic fundamentals - a fundamental is already a basic element
past history - history is already an account of the past
return back, revert back, descend down - the direction is inside the verb
at this point in time - four words for now
each and every - both words pick out members one at a time
final outcome, end result - an outcome is already what a process ends with
advance planning - planning is always done in advance
collaborated together - co- already means together
consensus of opinion, 6 a.m. in the morning, green in color, unexpected surprise

Redundancy can also sit across a comma. If the opening clause has already given the reason, an ending that repeats the reason is redundant even though no single phrase looks repetitive on its own.

Wordy constructions

These are longer frames built around a word that already exists. When you see one, ask what single word it is standing in for.

due to the fact that, owing to the fact that → because
despite the fact that → although
in the event that → if
during the time that → while
prior to the start of → before
for the purpose of building → to build
has the ability to → can
has a tendency to → tends to
on a daily basis → daily; in a careful manner → carefully; at a rapid rate → rapidly
is a person who paints → a painter
there were three geologists who mapped → three geologists mapped

Two tells cover most of them: the fact that almost always signals a conjunction written the long way, and on a ... basis / in a ... manner almost always signals an adverb written the long way.

Precision: the exact word, not the impressive one

The other half of this question type is not about length at all. Four choices differ slightly in meaning, and only one states the relationship the sentence actually describes. Read the rest of the sentence first - the evidence is almost always in the clause on the other side of a colon, a dash, or a rather than.

Cover crops will not ______ erosion on a slope this steep, but they will slow it enough to matter.
The second clause concedes a partial effect, so the negated verb has to be an absolute one: eliminate. Mitigate and reduce both mean slow it a little, so denying them contradicts the rest of the sentence.

Near-synonyms the ACT likes

fewer (counted) / less (measured); number of people / amount of water
imply (a speaker suggests) / infer (a listener concludes)
continual (repeated, with gaps) / continuous (unbroken)
disinterested (no stake) / uninterested (no interest)
flout (defy a rule) / flaunt (show off)
proscribe (forbid) / prescribe (direct that something be done)
historic (significant) / historical (of the past)
economical (thrifty) / economic (of the economy)
credible (believable) / credulous (too ready to believe) / creditable (praiseworthy)
ambiguous (open to two readings) / ambivalent (of two minds)
simple (uncomplicated) / simplistic (oversimplified - always a criticism)
tortuous (winding) / torturous (agonizing)
correlated (moving together) / caused (one produces the other)

Connotation counts as precision. Notorious, renowned and celebrated all mean widely known, but only notorious fits a road famous for pileups. And a bigger word is worth its extra letters only when it changes the meaning: utilize earns its place only when something is being put to a use it was not designed for. Otherwise it is just use in a costume.

How to work one of these

Read the whole sentence, including the clause after the punctuation. That clause usually decides it.
Ask whether the choices differ in meaning or only in length.
If only in length, take the shortest that keeps every fact and sounds like English.
If in meaning, name the relationship the sentence describes, then find the word for it.
Substitute your answer back in and read the sentence start to finish.
