The sentence given is divided into four parts. Identify the part with an error:
We have purchased (1) / many items of furnitures (2) / for our (3) / new flat (4).
Show Hint
"Furniture" is uncountable, so use "pieces of furniture" instead of "furnitures."
The phrase "many items of furnitures" should be corrected to "many pieces of furniture." "Furniture" is an uncountable noun, so it does not take a plural form.
