From the sentences provided below, identify the one that contains a grammatical error. If you find all of the sentences to be grammatically correct, select 'All are correct' as your response.
Correct Answer :
Microsoft has been enhancing cloud security and streamline remote work solutions.
Solution :
The correct option is: "Microsoft has been enhancing cloud security and streamline remote work solutions."
Explanation:
This sentence contains a grammatical error related to parallel structure (parallelism).
When two or more verbs are joined by a coordinating conjunction such as "and", they must follow the same grammatical form.
In this sentence, the auxiliary verb construction "has been" sets up the present perfect continuous tense.
The first action connected to "has been" is:
• enhancing (present participle / "-ing" form)
The second action linked by "and" should also maintain the present participle form to remain parallel:
• streamlining (instead of the base verb streamline)
Corrected Sentence:
"Microsoft has been enhancing cloud security and streamlining remote work solutions."
Analysis of Other Options:
• "This will be a promising decade of innovation for strengthening the global market." – Grammatically correct.
• "A severe blizzard is a dangerous storm and poses a significant threat to local wildlife." – Grammatically correct.
• "Industrial operations discharge massive quantities of greenhouse gases through coal combustion." – Grammatically correct.
