Short Answer 
The correct word to fill in the blank in the sentence “She came to live here ____ a month ago” is “almost,” as it effectively conveys the duration of time. Other options like “quite,” “beyond,” “over,” and “already” either do not fit or require rephrasing, making “almost” the most suitable choice.
Step 1: Analyze the Sentence Structure
Begin by examining the original sentence, “She came to live here ____ a month ago.” Understanding its context is crucial to selecting the appropriate word. The blank requires a term that effectively conveys a time duration and fits naturally within the sentence.
Step 2: Evaluate the Options
Next, assess each option to determine its suitability. Consider the following:
- Almost: Fits well with the period being discussed.
- Quite: Not appropriate before specific time expressions.
- Beyond: Does not accurately describe the time frame.
- Over: Indicates duration but is not as precise as “almost.”
- Already: Requires rephrasing of the sentence to be correct.
Step 3: Choose the Correct Option
After evaluating all options, the best choice is almost. This term is commonly used when referring to the passing of time, as in “I came back home almost a week ago.” It encapsulates the meaning intended in the sentence and maintains clarity.
