Explanations:The conjunction "so...that" is used to express a strong relationship between two parts of a sentence. The first part of the sentence describes a condition or situation, and the second part describes the result or consequence of that condition. The structure of the "so...that" construction is "so + adjective/adverb + that + clause." This construction is used to emphasize the degree of the adjective or adverb and to show the direct result of that degree.
In the given sentence, "Bengaluru roads are so narrow that they cannot bear the traffic," the adjective "narrow" is emphasized by "so," and the clause "they cannot bear the traffic" follows "that" to show the consequence of the roads being very narrow. This structure effectively conveys the idea that the narrowness of the roads is the reason they cannot handle the traffic.
It is important to note that the structure "so + adjective/adverb + that + clause" must be maintained for the sentence to be grammatically correct. Any deviation from this structure, such as placing "very" after "so" or placing "so" after "very," would make the sentence incorrect. Additionally, the subject-verb agreement must be maintained in the clause following "that." In this case, "they" (referring to the roads) is the subject, and "cannot bear" is the verb phrase, which is correctly used.
Understanding and correctly using the "so...that" construction is essential for clear and effective communication in English. It allows for the precise expression of cause and effect relationships and helps to emphasize the degree of the condition being described.
