Question: You are implementing an ASP.NET application that makes extensive use of JavaScript libraries. Not all pages use all scripts, and some scripts depend on other scripts.

Which two actions should you perform (Each correct answer presents part of the solution. Choose two.)

1. In your site’s master page, add a call to Sys.loader.defineScripts to define each of the scripts that are used in the site.
2. In your site’s master page, add a call to Sys.loader.registerScript to define each of the scripts that are used in the site.
3. In each page that uses scripts, add a call to Sys.get for each script that is needed in that page.
4. In each page that uses scripts, add a call to Sys.require for each script that is needed in that page.
