In the event that only one programming language was chosen as the standard, what kinds of justifications may be given for this decision?

To what extent does the possession of the ability to acquire additional programming languages benefit a programmer who already possesses knowledge of a diverse range of programming languages?

In what ways might expanding one's repertoire of programming languages be useful beyond mastery of one or two?

All languages have specific design criteria, a goal in mind. Give two languages that are in direct conflict with each. Provide examples of these conflicts as either programming examples (features allowed or not allowed) or program model, (environment). Compare and contrast the terms readability and writability regarding your selected two languages and explain why you believe this is so.
