1. It's a new kind of athletic shoe.
(Kinda is a slang word for saying similar to, it does not fit this sentence.)
2. The bird is feathering its nest.
(It's is a contraction of the words it is, so if we say the bird is feathering it is nest, it is incorrect.)
3. Clare ATE a baloney sándwich for lunch.
(Bologna is a city in Italy.)
4. That the color really complements your eyes.
(Compliments are to express praise, admiration, and are in general a positive remark. These two words are mixed up all the time. Complements, our answer, show how one thing enhances the other. So because the color enhances the eyes, we say it complements.)
I hope this helps! :)
