Question 1

Sentence improvement (remove erroneous “to” before a noun): use the correct verb–object pattern  Original sentence: "One of my drawbacks is that I do not have ___ tolerance of ambiguity."  Choose the option that correctly completes the expression.

Accepted Answer

Given dataIncorrect fragment in the prompt: “do not have to tolerance …” (an ungrammatical “to” before a noun).Concept/ApproachThe verb–object pattern is have + noun (“have tolerance”), not “have to tolerance.” We remove the stray “to.”Step-by-step correctionUse “I do not have tolerance of ambiguity.”(Note: In idiomatic English, “tolerance for ambiguity” is even more natural, but that preposition change is beyond the scope of the given options.)Option analysisdo not have — correctly removes the erroneous “to” and preserves meaning. ✅cannot have — changes meaning (ability vs. possession).am not — wrong verb; needs “have.”did not have to — wrong tense and still introduces “to.”No correction required — the original is ungrammatical.Final Answer“… I do not have tolerance of ambiguity.”

Question 2

Sentence improvement (modal perfect and adverb placement): verify that the sentence is already correct  Original sentence: "They should have calmly thought of the advantages that would accrue to them."  Decide whether a correction is needed; if not,…

Accepted Answer

Why the original is correctThe structure should have + past participle (should have thought) correctly expresses a past advisability. The adverb “calmly” is well placed before the main verb (thought). The phrasal verb “think of (the advantages)” is standard, and “that would accrue to them” is a correct relative clause.Option analysis (errors)should have been calm in thinking about — clumsy and changes the predicate structure.should be calmly thought of — passive; changes the subject and meaning.shall have to calmly thought of — tense/aspect errors and ungrammatical form after “to”.should have calmly think of — wrong form; needs past participle “thought”.Final AnswerNo correction required

Question 3

Sentence improvement (partitive with a superlative): ensure plural head noun after “the easiest of …”  Original sentence: "The easiest of the ___ to do is to ask the address to the postman."  Choose the option that correctly completes the partitive …

Accepted Answer

Given data & targetWe need a grammatically correct continuation after “The easiest of the …”.Concept/ApproachAfter “the easiest of the …”, the head noun must be plural: things. The natural, concise completion here is “the easiest of the things to do …”.NoteAlthough idiomatic English would say “ask the postman for the address,” the test item focuses solely on fixing the partitive phrase.Option analysisof the things to do — correct plural head; preserves meaning. ✅among the things did / thing to be done / of all the things done — tense/number/meaning issues.Final Answer“The easiest of the things to do …”

Question 4

Accepted Answer

TimelineMain action: “We demonstrated …” (simple past).Earlier action: preparation of artistic patterns occurred before that demonstration.Concept/ApproachTo show an action completed prior to a past reference point, use the past perfect: had prepared.Option analysishad prepared — correct backshift and aspect. ✅are prepared / are preparing — present (simple/progressive); wrong time.have prepared — present perfect; wrong reference time.Final Answer“… how we had prepared the artistic patterns.”

Question 5

Sentence improvement (adverb form): choose the correct adverb after a passive verb  Original sentence: "Because of his mastery in this field, his suggestions are ___ accepted."  Select the option with the correct adverb form.

Accepted Answer

ConceptAfter a passive verb (are accepted), we need an adverb to modify the verb phrase: “widely accepted,” not “wide accepted.”Step-by-stepForm: be + past participle → add adverb “widely.” ⇒ “are widely accepted.”Option analysisare widely accepted — correct auxiliary + adverb + participle. ✅widely acceptance — noun; wrong category.have widely accepted — active voice; subject mismatch.have been wide accepted — adjective “wide” instead of adverb “widely.”Final Answer“… his suggestions are widely accepted.”
