How did the Etruscans influence Roman science?

The Etruscans taught the Romans both engineering and building skills.

Explanation: The Etruscan civilization was an early civilization (900 BCE-100 BCE) that inhabited Italy from Tuscany to Rome. They made defining contributions to the history of Europe, because they shaped in many ways the early development of Rome. Many of the most distinctive features of Roman society were influenced by or directly borrowed from the Etruscans. This can be seen in its engineering, religion, culture and urban planning.

The Etruscans developed the economy of the city using scientific procedures by draining the marshes adjacent to Rome. They would also build cuniculi (which are ancient diversionary water channels) to carry water to their cities.

depends on the age of the teen, many believe by the age of 16 a person should know the strong difference between right and wrong along with the difference between risky and immediate death. swimming with sharks might be dangerous but swimming with sharks while bloody meat is attached to you is just insane. even more if you have no idea what you're doing. however, no matter the age, as long as the person is skilled enough and has the mental and physical capacity to control their actions doing whatever sport they put their mind to is all that matters.
