Choose the most suitable option to replace the highlighted part of the sentence: This building is built from bricks.
- (a)is made by bricks
- (b)has built of bricks
- (c)is built of bricks
- (d)is constructed with bricks
Answer
Why
Correct — C. The trigger is the preposition after built, which names the material.
Longman's note on made of and made from draws the line: of when the material 'has not been changed and can still be recognized' (a table made of wood), from when it has been completely changed (cheese made from milk).
For built, Longman gives be built of something, 'to be made using particular materials': 'The church was built of brick.'
Bricks are still bricks in the finished building, so the phrase is is built of bricks → option (c).
Why the others are wrong
- (a)is made by bricks — By names who or what does the making, the agent: a wall built by masons. Bricks are the material, not the maker, so 'made by bricks' misstates their role.
- (b)has built of bricks — Has built is active present perfect: it says the building did the building. The sentence needs the passive is built, because the building is what was built.
- (d)is constructed with bricks — Constructed with rewrites the verb as well as the preposition. The fault in the highlighted part is the preposition alone, and built of corrects it while keeping the sentence's own verb.
Concept
The preposition after made or built tells you how the material relates to the finished thing. Of marks a material you can still see in it: a ring made of solid gold, a building built of bricks.
From marks a raw material the process has transformed: cheese made from milk, a drink made from cherries. Ask whether the material survives unchanged.
Longman says from is used 'especially' for changed materials, so it states a preference rather than a ban, and that preference is what this item tests.
Option (d) is not ungrammatical. It loses to (c) because the highlighted part has one faulty word, the preposition, and (c) corrects it without rewriting the verb.
Key facts
- Made of or built of: the material is unchanged and still recognisable (a table made of wood).
- Made from: the material has been completely changed (cheese made from milk).
- By after a passive verb names the agent, the doer, not the material.

Common traps
- Choosing constructed with because it sounds more formal, when the fault is only the preposition.
- Reading made by as a material phrase: by names the maker, not what the thing is made of.
