Final answer:
Pizza was indeed invented in Italy, but only after tomatoes were introduced to the country in the 1500s. Similarly, German potato salad only came about after the introduction of the potato to Europe.
Step-by-step explanation:
The statement that pizza was invented in Italy is true. While the basic concept of flatbread with toppings has ancient roots, the pizza as we know it today—with tomato sauce—could not have been developed until after tomatoes were introduced to Italy in the 1500s. Similarly, other European food items like German potato salad came into existence only after new world crops such as the potato were introduced to Europe during the same time period.
