Final answer:
Both authors would likely agree that pizza originated in Naples, Italy and that the pizza we eat today is different from the pizza of long ago.
Step-by-step explanation:
BOTH authors would LIKELY AGREE with the statement: b) Pizza originated in Naples, Italy.
Based on the information provided, the texts mention that pizza was introduced to Italy and Naples is known as the birthplace of pizza. The texts do not mention Germany or America as the origin of pizza, so options a) and c) can be ruled out. Additionally, the texts mention that the pizza we eat today is different from the pizza of long ago, indicating that the authors would likely agree with statement d) as well.
