Its, Fewer, and Affect: Native Speaker Mistakes

Some English word pairs are so tricky that even native speakers mix them up on a daily basis. Do you know the difference between saying "the potion will affect you" and "it has a strange effect"? Or that you should use fewer for countable items (like "fewer eggs") but less for uncountable concepts (like "less salt")? And, of course, there is the classic mix-up between it's (meaning "it is") and the possessive its (as in "its favorite bone").

In this challenge, you will step into the shoes of mad scientists, frustrated appliance owners, and grammar-obsessed supervillains to master these confusing pairs. You will navigate quirky sentences to properly apply its vs. it's, fewer vs. less, and affect vs. effect. You'll work through 13 questions featuring a fun, varied mix of single-choice, multi-choice, drag-and-drop, and drop-down formats.
