question 7
which information is not in the article?
a. why camels were often better for travel than early wheels
b. who invented mechanical clocks with tiny wheels
c. how the wheel made it easier to create pottery
d. when people first began to use wheelbarrows

Explanation:

Without the actual article, we need to analyze each option based on general knowledge of wheel - related topics. Option A about camels vs early wheels, Option C about wheels and pottery, and Option D about the origin of wheelbarrows are common topics related to the wheel. However, the inventor of mechanical clocks with tiny wheels is a more specific and less common topic in general wheel - related discussions and is likely not covered in a general article about wheels.

Answer:

B. Who invented mechanical clocks with tiny wheels
