Final answer:
In the desert, Moses and the Hebrews ate manna, which is biblically described as a type of bread. The festival of Sukkot reflects their agricultural background, which became symbolic in urban life as the Hebrews settled in cities.
Step-by-step explanation:
In the desert, Moses and the Hebrews ate manna, which is described in the Bible as a type of bread. When the question asks what manna is, the correct answer is b) bread. This substance is said to have sustained the Israelites during their travels in the desert after escaping from Egypt.
The Hebrews originally had agricultural roots, which is reflected in many of the laws given to Moses. These included various food practices and festivals, such as the festival of Sukkot, which was related to harvest. Over time, as the Hebrews settled in cities, these agricultural laws took on a more symbolic role in religious practices.
