The correct answer for this question is "Perhaps" or "Maybe".

### I visited the front of Michael Jackson’s family house. It’s huge. That _____ means they are very rich. (strong possibility)

Explanation
The given sentence implies a strong possibility that Michael Jackson's family is wealthy based on the observation of their large house. To express this strong possibility in the sentence, we need a word that conveys a high level of certainty. The word "certainly" is an adverb that means "definitely" or "without a doubt." Using the word "certainly" in the given sentence emphasizes the speaker's belief that the size of the house is clear evidence of the family's wealth. So, by saying "That certainly means they are very rich," the speaker is expressing a strong conviction that the large size of Michael Jackson's family house is a clear indication of their wealth.

The use of "can't have" suggests that it was not possible for them to have given enough water, indicating a lack of ability or opportunity.
