Your best friend is packing for his new college dorm, but his grammar is as messy as his room! Select ALL the items on his packing list that are written with the correct plural forms.
The correct answers are Three heavy boxes of books and Several comfortable pillows.
In English, you must add -s or -es to show that there is more than one countable item (boxes, books, pillows).
However, uncountable nouns like furniture, information, or water do not take an -s. "Two new wooden furnitures" is incorrect; you would say "Two pieces of wooden furniture."
