I’m not sure if you mean technological and economic development or just products coming out kind of development.

Answer:
a: eat at a restaurant and hear a speech
Explanation:
Individuals who went to Rome's forum were likely to eat at a restaurant and hear a speech. This is because the Forum was the city's center and was mainly a public area/marketplace, in which commercial, religious, economic, political, legal, and social activities took place on a day to day basis, such as restaurants and political speeches. Fora are extremely common in all Roman cities, but Rome's forum was the biggest and most well known of them all.
The correct answer is "It's a primary source because it's firsthand information".
When we're presented with a statistical study of a certain topic, we're dealing with hard facts. A statement addressing "Percentage of College Degrees Awarded to Women" isn't making any assumptions on the matter and the tone of the phrase is neutral as opposed to personal (like you would find in a diary for example). Also, it's not an opinion that someone is giving through speech, but rather the expression of a mathematical calculation that someone made through the observation of certain data firsthand. That's why it is a primary source.
Hope this is helpful!
