Final answer:
The passage does not mention tomatoes as toppings in the 1700s, and it explains that tomatoes started appearing in the 1800s. By the early 1900s, canned tomatoes were available year-round.
Step-by-step explanation:
The best evidence to support the statement that people did not put tomatoes on their pizza in the 1700s is the mention that toppings for early Neapolitan pizzas in the 1700s included olive oil, garlic, oregano, grated cheese, lard, and salt, but there is no mention of tomatoes being used. The passage further explains that when tomatoes started appearing on pizzas in the 1800s, they would have only been used during their fresh season or as a conserva. It wasn't until the early 1900s when commercially canned tomatoes became available year-round in southern Italy.
