"The new policy will definitely _____ employee morale."
The correct answer is affect.
"Affect" is typically a verb meaning "to influence or have an impact on." "Effect" is usually a noun meaning "a result." Here, we need a verb after "will," so "affect" is correct. Remember: Affect = Action (verb), Effect = End result (noun).
The correct answers are affect, effect, affect, and effect.
"Affect" is typically a verb meaning "to influence" (temperatures influence migration). "Effect" is typically a noun meaning "result" (the result on polar bears). "Affect" is again the verb (pollution will influence ecosystems). "Effect" as a verb means "to bring about" or "to cause" — here, policies will bring about positive change. This is the trickiest usage!
The correct answers are The rainy weather didn't affect her cheerful mood, What effect did the movie have on you?, and Lack of sleep can affect your concentration.
"Affect" is typically a verb meaning "to influence," while "effect" is typically a noun meaning "a result." In the incorrect sentences, "affect" should be "effect" because a noun is needed after "a negative" and "an immediate."
Drag the correct words to help this student finish their essay about school leadership.
"The new principal announced several policy changes last week. Many students wondered how these decisions would affect their daily routines. The effect was immediate: homework decreased, but expectations for classroom participation increased. As a matter of principle, I believe leaders should always explain their reasoning."
The correct answer for the first blank is principal.
"Principal" (noun) means the head of a school. Don't confuse it with "principle" (a belief or rule). The correct answer for the second blank is affect. "Affect" is typically a verb meaning "to influence." The decisions would influence their routines. The correct answer for the third blank is effect. "Effect" is typically a noun meaning "result" or "outcome." Here it describes the immediate result. The correct answer for the fourth blank is principle. "Principle" (noun) means a fundamental belief or rule. "As a matter of principle" is a common expression.
The correct answers are It's been a long day at work, Whose umbrella is this?, The company changed its logo last year, and Who's coming to the party tonight.
"It's" = it is or it has (contraction), "its" = possessive (belonging to it). "Who's" = who is or who has (contraction), "whose" = possessive (belonging to whom). In "The dog wagged it's tail," the possessive "its" is needed. In "Who's turn is it," the possessive "whose" is needed.
The correct answers are There, your, They're, and you're.
"There" introduces existence ("there are..."). "Your" is the possessive form (your orders = orders belonging to you). "They're" is the contraction of "they are" (they are delicious). "You're" is the contraction of "you are" (you are going to love them).

"Dear Mom, I finally made it to Paris! There are so many beautiful sights here. The locals are friendly, and they're always willing to help with directions. I visited the Louvre yesterday and saw their famous Mona Lisa. Wish you were here!"
The correct answer for the first blank is There.
"There" is used to indicate existence or location ("There are so many sights"). The correct answer for the second blank is they're. "They're" is the contraction of "they are" ("they are always willing"). The correct answer for the third blank is their. "Their" shows possession ("their famous Mona Lisa" = the Mona Lisa belonging to the Louvre).
The correct answers are They're planning a surprise party for their mom, There are three cookies left in the jar, and I saw their car parked over there.
"They're" = they are, "their" = possessive (belonging to them), "there" = a place or used with "there is/are." In the incorrect options, "there" should be "their" (possessive), and "Their" should be "They're" (they are).

"_____ going to love the surprise we have planned at _____ house over _____."
The correct answer is They're / their / there.
They're = "they are" (contraction) — "They are going to love..." Their = possessive — "at their house" (the house belonging to them) There = a place — "over there" (indicating location) This tricky trio trips up even native speakers!
Your crush just texted you, but autocorrect has struck! Which version should you send back to prove you're grammar-savvy and date-worthy?
