Explanation: "The company" is a singular collective noun, requiring the singular form "is." The phrase "is planning on" + gerund (expanding) is the correct structure for expressing future intentions in business English.
Explanation: "By the end of this quarter" indicates a future time point, requiring the future perfect tense (will have + past participle) to show an action that will be completed before that specific time.
Explanation: "The board of directors" is treated as a single entity in business English, requiring the singular "has." The adverb "unanimously" is correctly placed between the auxiliary verb and the main verb.
Explanation: This is a first conditional sentence expressing a real possibility. The structure requires the simple present tense in the if-clause ("approves") and "could" + base verb in the main clause.
Explanation: "For" is used with a duration of time (three months). "Since" is used with a specific point in time (since January). The present perfect continuous tense with "for" indicates an ongoing action.
Explanation: "Than" is used after comparative adjectives (higher) to show comparison between two things. "Then" refers to time, while "as" is used with "as...as" constructions.
Explanation: After verbs of request, demand, or suggestion (requested, demanded, suggested), we use the subjunctive mood with the base form of the verb "be," regardless of the subject.
Explanation: "Despite" is followed by a noun phrase (the economic downturn). "Although" and "even though" require a complete clause with a subject and verb. "However" is used to connect two sentences, not within a sentence.
Explanation: "Need" requires the passive infinitive form "to be + past participle" when the subject (the contract) receives the action. The contract doesn't review itself; it needs to be reviewed by someone.
Explanation: The verb "appreciate" is followed by a gerund (verb + -ing), not an infinitive. This is a common pattern with verbs of liking and preference in business English.
Explanation: With "neither...nor" constructions, the verb agrees with the noun closest to it. "Employees" is plural, so we use "were." The past tense is appropriate here for describing a past situation.
Explanation: "So...that" is used to show cause and effect with adjectives or adverbs. "Such...that" is used with nouns. The structure is: so + adjective + that + result clause.
Explanation: This is a third conditional sentence expressing an unreal past situation. The structure requires: if + past perfect (had invested) in the if-clause, and would have + past participle (would have surpassed) in the main clause.
Explanation: "Which" is used in non-defining relative clauses (with commas) to refer to the entire preceding clause. "That" cannot be used after a comma in this type of clause. "Which" adds extra information about the whole situation.
Explanation: "Required" is followed by the infinitive form "to + base verb." This is the standard pattern for expressing obligations and requirements in formal business English.
