Intermediate Level Common Errors Quiz

"The salary of a doctor" (a monetary amount) is being compared with "a teacher" (a person — different category). The comparison must be parallel: salary vs salary. Correct sentence: "The salary of a doctor is higher than that of a teacher." "That of a teacher" substitutes for "the salary of a teacher." This illogical comparison error (attribute vs. entity) is one of the most reliably tested intermediate errors in SSC CGL error spotting. Always check that both sides of "than" belong to the same logical category — salary vs salary, not salary vs. person.

"Unique" is an absolute adjective — it means "one of a kind" and cannot be graded. "Most unique" adds a superlative degree marker to an absolute — always wrong. A person is either unique or not — there are no degrees of uniqueness. "She is a unique artist of her generation" is correct. Absolute adjectives tested in exams: unique, perfect, complete, dead, empty, infinite, universal, fatal, unanimous. None of these can be graded with "most," "more," "very," "quite," or any other degree marker. The absolute adjective rule is tested at every level — "unique" is the most frequently appearing absolute adjective in SSC and IBPS papers.

"Senior" is a Latin-origin comparative adjective — it already contains the comparative meaning and must be followed by "to," not "than." Additionally, it never takes "more" — "more senior" creates a double comparative on an already-comparative adjective. The correct sentence is "He is senior to his colleague by three years." Latin comparatives tested in exams: senior to, junior to, superior to, inferior to, prior to, preferable to. None of these ever take "more" or "than." Two errors in option A: wrong degree marker ("more") + wrong connector (implied "than" instead of "to").

 "Between the two proposals" signals exactly two → comparative degree is required. "The most viable" is the superlative — reserved for three or more. "The more viable" is the correct comparative form for selecting the superior of exactly two. Correct sentence: "Between the two proposals, the second is the more viable option." "Between the two" is one of the most reliable trigger phrases for comparative degree — whenever it appears, any superlative in the same sentence is automatically wrong. This wrong-degree-for-two-items error is tested at both beginner and intermediate levels.

"The climate of Ooty" (a weather quality) is being compared with "Mumbai" (a city — different category). The comparison must be parallel: climate vs. climate. Correct sentence: "The climate of Ooty is more pleasant than that of Mumbai." "That of Mumbai" substitutes for "the climate of Mumbai." This illogical comparison is one of the most tested intermediate error types — the "climate of X vs. city Y" pattern appears in multiple SSC CGL papers. The "of" phrase in the subject is always the signal that a "that of" substitution is required on the comparison side

 "Perfect" is an absolute adjective — it describes a state of completeness that cannot be exceeded. "Most perfect" grades an absolute — always wrong. A candidate is either perfect for the role or not — there are no degrees of perfection. "She is the perfect candidate for the role" is correct. This tests the same absolute adjective rule as Q2 — now applied to "perfect" instead of "unique." Both "unique" and "perfect" are the two most tested absolute adjectives in Degrees of Comparison error spotting. Adding "most," "more," "very," or any other degree marker to either is always wrong.

 "Inferior" is a Latin-origin comparative adjective — it already contains the comparative meaning. Adding "more" creates a double comparative on an already-comparative adjective — always wrong. "Inferior to his predecessor" is correct — no "more" needed. "To his predecessor" correctly uses the Latin comparative connector "to" — no error there. "In terms of management skills" correctly specifies the dimension — no error there. The error is exclusively "more" before "inferior" in option A. Latin comparatives are already comparative by nature — adding "more" is like saying "more taller" — redundant and always wrong.

 "Of the three candidates" signals three or more → superlative degree is required. "The more experienced" uses the comparative — wrong for three or more. "The most experienced" is the correct superlative form. Correct sentence: "Ramesh is the most experienced of the three candidates." The group size rule: "of the three" always triggers superlative. "The more experienced of the two candidates" would be correct if exactly two were being compared. The number word in "of the three" is the definitive trigger — three → superlative, two → comparative.

 "Her handwriting" (a quality) is being compared with "her sister" (a person — different category). The comparison must be parallel: handwriting vs. handwriting. Correct sentence: "Her handwriting is better than that of her sister" or "Her handwriting is better than her sister's." "That of her sister" or the possessive "her sister's" correctly substitutes for "her sister's handwriting." The handwriting/person category mismatch is a standard intermediate illogical comparison question — the "her" in both subject and comparison creates a proximity trap that makes the error easy to miss on quick reading.

"Preferable" is a Latin-origin comparative adjective — it already contains the comparative meaning and must be followed by "to." Adding "more" creates a double comparative on an already-comparative adjective — always wrong. "This plan is preferable to the earlier one" is correct. "To the earlier one" correctly uses the Latin comparative connector "to" — no error there. Latin comparative set with "to": preferable to, superior to, inferior to, senior to, junior to, prior to. None take "more" — they are already inherently comparative.

"One of the + superlative + plural noun" requires the noun to be plural. "Scientist" is singular — it must be "scientists." "The most brilliant" correctly forms the superlative of the three-syllable adjective "brilliant" with the mandatory "the" — no error there. "In the department" correctly specifies the scope — no error there. The error is exclusively the singular "scientist" in option B — it must be "scientists." Memory hook: "one of the most + adjective + PLURAL noun" — you are referring to one member of a group, so the group noun must be plural.

"The results of our team" (performance outcomes — plural attribute) are being compared with "the rival team" (an entity — different category). The comparison must be parallel: results vs. results. Correct sentence: "The results of our team are better than those of the rival team." "Those of the rival team" correctly uses "those" (plural) to substitute for "the results of the rival team" — maintaining both logical parallelism and number agreement. "That" would be wrong here — "results" is plural, requiring "those." The plural/singular distinction in "that/those" substitution is a precision point that elevates this to intermediate level.

 If he works in his office, "anyone in his office" includes him — logical self-inclusion error. "Else" must be added after "anyone": "than anyone else in his office." "Else" is required after pronouns like "anyone/anybody/anything/no one" when the subject is a member of the comparison group. "More fluently" correctly uses "more" with the four-syllable adverb "fluently" — no error there. The error is exclusively the missing "else" in option B. The "else" rule is the "other" rule's counterpart for pronouns — both serve the same logical exclusion purpose.

"The population of India" (a demographic measure) is being compared with "China" (a country — different category). The comparison must be parallel: population vs. population. Correct sentence: "The population of India is more than that of China." "That of China" substitutes for "the population of China." This population/country illogical comparison is one of the most frequently appearing error types in SSC CGL passages — particularly in economics and geography-themed sentences. Always verify both sides of "than" belong to the same logical category before confirming no error.

"Of the two sisters" signals exactly two → comparative degree is required. "Most talented" is the superlative — wrong for two. "The more talented" is the correct comparative form. Correct sentence: "Of the two sisters, Maya is the more talented." Additionally, the mandatory "the" before the degree form is missing — "most talented" without "the" violates the superlative rule. Two errors in option B: wrong degree (superlative for two) and missing "the." The primary tested error is the wrong degree — superlative used where comparative is required because "of the two" triggers comparative.

"More wiser" is a double comparative — "wise" is a one-syllable adjective forming its comparative with -r (since it ends in silent -e): "wiser." Adding "more" creates a redundant double comparative — always wrong. "Anyone else" correctly uses "else" after "anyone" — no error. "In the research team" correctly identifies the group — no error. The error is exclusively the double comparative "more wiser" in option A — "wiser" alone is the complete, correct comparative form. One-syllable adjectives ending in silent -e: wise → wiser, large → larger, brave → braver — add -r only, never "more."

"Complete" is an absolute adjective — it describes a state of wholeness that cannot be exceeded. "Most complete" grades an absolute — always wrong. A report is either complete or not — there are no degrees of completeness. "This is the complete report the committee has produced" is the correct form (or using a different gradable adjective like "comprehensive"). "The committee has ever produced" correctly uses present perfect with "ever" in a superlative-like context — no error there. The error is "most" before the absolute "complete" in option A. Absolute adjectives: unique, perfect, complete, dead, empty, infinite — none can be graded.

"The infrastructure of State A" (a development quality) is being compared with "State B" (a state — different category). The comparison must be parallel: infrastructure vs. infrastructure. Correct sentence: "The infrastructure of State A is better developed than that of State B." "That of State B" substitutes for "the infrastructure of State B." "Better developed" is correctly formed — "better" is the irregular comparative of "well/good" used adverbially to modify "developed." The error is exclusively the category mismatch in option C — infrastructure vs. state. The formal administrative register of the sentence disguises a standard illogical comparison.

"Virat's batting average" (a statistical measure — singular) is being compared with "Sachin" (a person — different category). The comparison must be parallel: batting average vs. batting average. Correct sentence: "Virat's batting average is higher than Sachin's." The possessive "Sachin's" (implying "Sachin's batting average") is the most natural correction here. "That of Sachin" is also correct but less idiomatic for named individuals. This batting average/person illogical comparison appears frequently in cricket-themed exam passages — sport and performance contexts are favourite disguises for the illogical comparison error in intermediate-level questions.

Option C — "The output of Team A is higher than that of Team B" — is fully correct. Parallel comparison: output vs. output (using "that of"). "Higher" is the correct one-syllable comparative. Option A — "more taller" — double comparative — wrong. Option B — "the most unique" — absolute adjective graded with "most" — wrong. Option D — "more preferable" — double comparative on a Latin adjective — wrong. Option C is the only sentence that satisfies all Degrees of Comparison rules simultaneously — no double comparative, no absolute adjective violation, no Latin comparative error, correct parallel comparison, correct degree form.
