BK 25 L3 Grammar
| Question | Answer |
|---|---|
| Correct the error: The laboratory team has no intention to extract the remaining samples until next week. | ...no intention of extracting... (Rule: The noun 'intention' must be followed by the preposition 'of' + gerund, not an infinitive.) |
| Correct the error: Despite of the high-protein diet, he found it difficult to maintain his energy levels during the marathon. | Despite the high-protein diet... (Rule: 'Despite' functions as a preposition on its own and takes a noun phrase directly. Never use 'of' after 'despite'.) |
| Correct the error: Two-thirds of the newly manufactured medical equipment were found to be defective. | ...equipment was found... (Rule: For fractions followed by 'of', the verb must agree with the following noun. 'Equipment' is an uncountable noun, so it requires a singular verb.) |
| Correct the error: The principal advantage to use a local facility is the reduction in shipping delays. | ...advantage of using... (Rule: The noun 'advantage' often pairs with 'of' + gerund to define the specific benefit being discussed.) |
| Correct the error: The structural engineers investigated the cause for the collapse but found no evidence of a flaw. | ...the cause of the collapse... (Rule: Use the preposition 'of' to connect the noun 'cause' to its specific effect or event.) |
| Correct the error: The grammar assignment was incredibly steep and challenging, so she managed to complete it on time. | ...challenging, yet she managed to... (Rule: Use 'yet' as a coordinating conjunction instead of 'so' when the second clause presents a surprising or contrasting result.) |
| Correct the error: The laboratory technician forgot to turn off the ventilation system, yet the chemical fumes filled the room. | ...ventilation system, so the chemical... (Rule: Use 'so' to show a direct, logical cause-and-effect result. Fumes filling the room is a direct consequence of leaving the system off.) |
| Correct the error: The medical clinic does not accept personal checks, nor they take credit cards without a valid ID. | ...checks, nor do they take... (Rule: When 'nor' joins two independent negative clauses, it forces subject-verb inversion: nor + auxiliary verb + subject.) |
| Correct the error: He was about to extracting the damaged tooth when the patient suddenly asked a question. | ...about to extract... (Rule: The future-oriented structure 'be about to' must be followed immediately by the base form of the verb [V1], never a gerund.) |
| Complete the sentence: Pack your bags quickly! The tour bus is _______ leave for the historic site in five minutes. | about to (Rule: Use 'be + about to + base verb' to describe an action that will happen imminently in the very near future.) |
