Saying “those” when “the” will do is a pretentiousism. Here’s an example:
“As we continue to implement the Great American Outdoors Act across the Forest, our highest priorities will be those projects that reduce deferred maintenance, are ready to implement and provide the greatest immediate benefit to the public,” stated [Caribou-Targhee National Forest Branch Chief Wes] Stumbo.
Saying “will be the projects that…” is more straightforward than what’s in the quote. In fact, he could have said “…will be projects that…” because, after all, the proper emphasis is on projects, not on their decision-making process (or whatever it is that the word “those” emphasizes).
