What this topic is

Main idea questions ask what a whole passage is mostly about, or what central claim the author is making.

The right answer covers the entire passage, not one paragraph, and it matches the author's actual point rather than a topic the passage merely touches. SSAT Upper stems are often phrased around the passage's central claim or primary focus, followed by possible completions.

Wrong choices tend to be too narrow, describing a single detail that is true but minor, or too broad, making a sweeping statement the passage never supports. A helpful check is whether the choice would make a reasonable title for the passage as a whole.

Sample questions

Pick an answer to see whether it is right — nothing is saved, and nothing needs an account.

A city tree inventory begins with a simple

question: what is growing along the

streets? The answer is harder than it

sounds. Volunteers and arborists record

species, trunk size, condition, sidewalk

damage, overhead wires, and empty planting

spaces. Each tree becomes a data point in

a living system.

The inventory helps the city see patterns

that no single block reveals. One

neighborhood may have many old maples

nearing the end of their safe life.

Another may have few trees at all, leaving

sidewalks hotter in summer. A third may

depend too heavily on one species, making

it vulnerable if a disease attacks that

species.

The information changes maintenance

priorities. Crews can prune branches near

wires before storms, replace risky trees

gradually, and choose species that fit

narrow sidewalks. Planting becomes more

strategic when empty spaces are matched

with shade needs, soil limits, and future

growth.

The inventory is never finished. Storms,

pests, construction, and new plantings

change the urban forest each year. Still,

the list gives the city a way to care for

trees as shared infrastructure rather than

scenery. It also makes equity easier to

discuss. When the map shows which blocks

lack shade, the city can compare need

instead of relying only on complaints from

the loudest neighborhoods. A tree

inventory cannot plant a tree by itself,

but it can make the next planting harder

to ignore and easier to justify in public

budget meetings.

Question 1Mid

The passage’s central claim is that

a city tree inventory’s main job is to document sidewalk damage and overhead wires✗ Not this onetree inventories matter most in neighborhoods where old maples are near the end of their safe life✗ Not this onethe inventory is chiefly a way to stop neighborhoods from depending on a single species✗ Not this onethe inventory’s greatest use is answering complaints from the neighborhoods that speak up first✗ Not this onea city tree inventory guides maintenance and future planting decisions✓ Correct

Show answer

Answer: E — a city tree inventory guides maintenance and future planting decisions

The passage presents the inventory as a living record that reveals citywide patterns, resets maintenance priorities, and makes planting and equity decisions more strategic. Documenting sidewalk damage and wires is only one part of what volunteers record, not the inventory’s purpose. The old-maple neighborhood is one pattern among several, not the inventory’s main audience. Reducing one-species plantings is a vulnerability the data can expose, not the inventory’s chief aim. Answering the loudest complaints is what the map is meant to replace: it lets the city compare need instead.
