Archaeologists excavating an ancient Chi-Xua site found a small statue

Official Explanation

In the absence of more information about the use of sandstone in ancient Chi-Xua buildings, the fact that the building material was unusual does not, in itself, imply any particular function. This rules out the first option as the correct response for either selection. While the building in question did have an area of 30 square meters, the fact that it was a one-room building makes the third option irrelevant. Finally, even if it could be known with certainty that the bits of cloth were not part of ceremonial robes, the absence of ceremonial robes provides no evidence to suggest that the room served a residential function. Thus the fourth option is also irrelevant.

If red-and-white striped pottery was used almost exclusively for personal food storage, this strongly suggests that the room was a private space, such as a residence.

The correct answer is Red-and-white striped pottery was used in Chi-Xua almost exclusively for personal food storage.

If nearly all of the Chi-Xua residential buildings had multiple rooms, then strong evidence of residential use would be required to accept that this building is one of the few exceptions.

The correct answer is Nearly all Chi-Xua residential buildings had multiple rooms.
