Fill in the blanks with the appropriate transition.
Janice has a wonderful house, _________ it is in one of the most beautiful locations in the city.

The correct answer is: Furthermore

The transition 'furthermore' is used to add a piece of information or opinion that only adds to or supports what has already been said before. Here, the second clause 'it is in one of the most beautiful locations in the city' supports the first clause 'Janice has a wonderful house', and proves the point further.
