Incorrect. The word “historical” is an adjective, but the sentence requires the noun “history” to serve as the object of the preposition “in.” The phrase “in the human historical” is incorrect and should be “in human history.” Example: “This is the most important event in human history.” (Not: “This is the most important event in the human historical.”)

Incorrect. The sentence is grammatically correct. The subject “book” agrees with the verb “was,” the relative clause “that I borrowed from the library” is properly constructed, and the adjective “interesting” correctly modifies the subject. Example: “The movie that we watched last night was very entertaining.” (similar correct structure).

Incorrect. The correlative conjunction pair is “not only… but also,” not “not only… yet.” Therefore, “yet some of” should be replaced with “but also some of.” Example: “She is not only intelligent but also hardworking.” (Not: “She is not only intelligent yet also hardworking.”)

Incorrect. When two adjectives are joined by “and,” they should maintain parallel form. Since “more beautiful” is a comparative adjective, the first adjective “smart” should also be in comparative form to maintain parallelism. Therefore, “smart” should be replaced with “smarter.” Example: “She is taller and more athletic than her sister.” (Not: “She is tall and more athletic than her sister.”)

Incorrect. The sentence is grammatically correct. The phrase “My inclination is to think” is properly structured, the conditional clause “if you freeze something” uses the correct simple present tense, and the main clause “all the kinetic processes slow down” maintains proper subject-verb agreement. Example: “My tendency is to believe that if you work hard, you will succeed.” (similar correct structure).

Incorrect. The phrase “one of the” is always followed by a plural noun because it refers to one item from a group of many. Therefore, “region” should be replaced with “regions.” Example: “She is one of the most talented artists in the country.” (Not: “She is one of the most talented artist in the country.”)

Incorrect. The demonstrative adjective “these” is used with plural nouns. Therefore, the singular noun “period” must be changed to the plural “periods.” Example: “Artifacts from these eras provide valuable insights.” (Not: “Artifacts from these era provide valuable insights.”)

Incorrect. The infinitive is formed by “to + base form of the verb,” not “to + past tense.” Therefore, “to searched” should be replaced with “to search.” Example: “We use software to analyze the results.” (Not: “We use software to analyzed the results.”)

Incorrect. The sentence is grammatically correct. The participle phrase “Though dejected by the unexpected development” correctly modifies the subject “several monasteries,” and the rest of the sentence maintains proper structure and logical flow. Example: “Though disappointed by the sudden change, the team continued with their plan.” (similar correct structure).

Incorrect. The list of conditions after “If you’re” must maintain parallel structure using present participles (verb + ing). Since “struggling,” “having,” and “considering” are all in the list, “having” should be “having” but the error is that “having” should be “have” to match “struggling.” Actually, “having” is correct as a participle, but the correct parallel structure is “struggling… having… or considering.” The error is that “having” should be “have” to maintain the present continuous with “you’re.” Example: “If you’re eating healthy, exercising regularly, and sleeping well, you will feel better.” (Not: “If you’re eating healthy, exercise regularly, and sleeping well, you will feel better.”)

Incorrect. The structure “likely to” must be followed by parallel infinitives. Since “to degrade” is an infinitive, the second verb must also be an infinitive. Therefore, “generated” should be replaced with “generate.” Example: “The heat can cause materials to expand and release fumes.” (Not: “The heat can cause materials to expand and released fumes.”)

Incorrect. The relative pronoun “that” refers to “procedural lapses,” which is plural. Therefore, the verb must also be plural. “Needs” should be replaced with “need.” Example: “The issues that require attention are listed here.” (Not: “The issues that requires attention is listed here.”)

Incorrect. Using “more” before a comparative adjective like “stronger” is redundant. Either “more strong” or “stronger” should be used, not both. Therefore, “more stronger” should be replaced with “stronger.” Example: “This solution is far better than the previous one.” (Not: “This solution is far more better than the previous one.”)

Incorrect. The noun “experience” in this context is uncountable and does not require the indefinite article “an.” Therefore, “with an experience” should be replaced with “with experience.” Example: “She has experience in project management.” (Not: “She has an experience in project management.”)

Incorrect. The sentence is grammatically correct. It uses the third conditional structure “Had + subject + past participle” (inversion) to express an unreal past condition, and the main clause “could have been avoided” correctly uses the perfect modal passive. Example: “Had the warning been heeded, the disaster could have been averted.” (similar correct structure).

Incorrect. The past perfect tense is formed with “had + past participle.” Therefore, “hears” (present tense) should be replaced with the past participle “heard.” Example: “No one had ever seen such a phenomenon before.” (Not: “No one had ever sees such a phenomenon before.”)

Incorrect. After a modal verb like “could,” the base form of the verb must be used, not the past tense or past participle. Therefore, “could told” should be replaced with “could tell.” Example: “You could see from her smile that she was happy.” (Not: “You could saw from her smile that she was happy.”)

Incorrect. The subject “you” always takes the plural verb “have,” regardless of whether it refers to one person or more. Therefore, “you has” should be replaced with “you have.” Example: “You have a responsibility to be on time.” (Not: “You has a responsibility to be on time.”)

Incorrect. When two subjects are joined by “not only… but also,” the verb agrees with the subject closer to it. Here, “her parents” (plural) is closer, so the verb must be plural. Therefore, “is going” should be replaced with “are going.” Example: “Not only the teacher but also the students are excited.” (Not: “Not only the teacher but also the students is excited.”)

Incorrect. The subject “psychologists” is plural, so the verb must also be plural. Therefore, “believes” should be replaced with “believe.” Example: “Scientists believe that climate change is real.” (Not: “Scientists believes that climate change is real.”)
