The correct sentence that best corrects the dangling construction in the original sentence is: "When I am discouraged, the Bible provides blessed comfort."
Step-by-step explanation:
A dangling construction occurs when a phrase or clause is placed in a sentence without a clear subject or connection to the main clause. In the original sentence, the phrase "When discouraged" is a dangling construction because it is not properly connected to the main subject.
To correct this, we need to provide a clear subject for the phrase. Option 1, "When discouraged, the Bible provides a blessed comfort," is not the best choice because it still leaves the subject unclear. Option 2, "When discouraged, the Bible provides a comfort blessed," changes the meaning by placing the emphasis on the comfort itself rather than the blessing. Option 4, "The Bible, when discouraged, provides a blessed comfort," is better but still separates the subject from the verb.
The best option is Option 3, "When I am discouraged, the Bible provides blessed comfort." This sentence connects the phrase "When I am discouraged" to the subject "I," making the subject clear and resolving the dangling construction. Additionally, the placement of "blessed" before "comfort" maintains the intended meaning of the original sentence.
