Questions

In git, which is the term used for making a local copy of a remote repository, branch, clone, or fork? (one word)
In git, pushes to the main repository can be dangerous because they can cause file conflicts, add unwanted changes, and cannot be easily undone. (true/false)
Augmenting a built-in type in JavaScript uses the same syntax as adding a method to a regular object. (true/false)
Read access to unqualified symbols are resolved by looking at the symbols defined in the inner most function context outward until the global function context is reached. (true/false)
Read access to object properties are resolved by looking at the object's properties and then by looking at the chain of objects pointed to by the objects on the prototype chain. (true/false)
