When using "you" or "one" as the subject of a sentence, you need to be consistent. Because the first half of this sentence uses "you" as the subject, the second half must also use "you"—not "one."

Sentences must consistently use either "you" or "one" as the subject, and because this sentence identifies "you" as the subject in the first clause, the second clause must also use "you" (not "one").

This sentence uses both "you" and "one" to give general advice. These should be kept consistent. The corrected sentence reads, "One should always guard one's valuables when traveling in a crowded place."

The words "one and "you" are both acceptable pronouns, but they should not be used as pronouns in the same sentence because the third-person pronoun "you" does not agree with "one."

This sentence uses both "one" and "you" as pronouns. These should be kept consistent—that is, if a sentence uses one of these pronouns, it should not suddenly start using the other afterwards. Changing "your" to "one's" corrects the sentence's error. The corrected sentence reads, "One should never underestimate the worth of double-checking one's work."

This sentence switches between using the second-person pronoun “your” and the general pronoun “one.” These should stay consistent; if you begin by using one of these words as a pronoun in a sentence, you shouldn't suddenly switch to using the other. The corrected sentence reads: "Although learning to balance on your head may be challenging at first, the sense of accomplishment you feel after finally mastering the skill is worth all of the effort."

This sentence first introduces the possessive pronoun "one's" in "one's taste expectations," but later, it switches to using the possessive pronoun "your" in "your prior experience with foods of various colors and textures." If you begin using one of these pronouns in a sentence, you should be consistent and only use that pronoun in that grammatical situation for the rest of the sentence; switching from one to the other mid-sentence is grammatically incorrect. To correct the sentence, you could either change "one's" to "your" or "your" to "one's"—either swap would result in a consistent use of one of the pronouns. One version of the corrected sentence would read, "The research study supported the theory that one’s taste expectations are based off of one’s prior experience with foods of various colors and textures."

In this sentence, the pronouns do not stay consistent. It starts out with the subject “one” and changes to the possessive “your,” but these should refer to the same thing. The corrected sentence reads, "One should never allow one’s work responsibilities to be taken over by another person."

The subject of the sentence is not consistent throughout the sentence.  At the beginning of the sentence, it refers to "one" but later changes to "you."  As changing the word "you" that is used later in the sentence is not an option, "one" is the incorrect word in this sentence. The sentence should read, "You cannot see the conditions in a sweatshop and truthfully say you think they are acceptable work conditions for any human being."

In this sentence, the pronouns do not stay consistent. It starts about speaking generally about “one,” then switches to a second-person “you.” The corrected sentence reads, "One might try to adopt a baby lion, but one should be prepared for it to become quite ferocious when it grows up."
