Advanced One / Ones Substitution Exercises

Advanced one and ones substitution goes beyond simple adjective phrases. You can use one and ones with determiners, identifying phrases, and relative clauses: which one, the one I bought yesterday, the ones near the park, each one, and every one. These patterns help you refer to a specific countable noun without repeating it. For example, "I've read two articles; the one about climate policy was the clearest" identifies one article from a set.

The noun still has to be countable. With uncountable nouns such as rice, water, traffic, and advice, use some or a countable container: "Would you like some rice?" not "Would you like one?" Possessive forms need care too. We usually say my old one or your smaller ones, but not my one when no adjective or identifying phrase follows. This exercise practises determiner choices, relative clauses, and cases where one/ones is not suitable. The nearby determiner usually tells you whether a replacement is natural.
