The answer is C. You may use a semicolon to combine two sentences when the information in both are closely linked. You cannot use a comma as that would make it a run-on. Just simply adding ‘and’ to combine would make it a run-on as well. You cannot use a semicolon with the coordinating conjunction ‘and’ as this is not correct. You would use a comma with ‘and’ to combine the two sentences.
The answer is letter C. juncture... domicile
The word juncture means a certain point or moment in time, while domicile means a home.
It would be the same as saying, 'At this point in my life, I think it is time to go live in my own home where I can keep house for myself.'
Keep house is expression meaning the same as doing house chores, such as cooking, cleaning, doing the laundry etc.
