During the Visualforce Page execution, what step follows immediately after "Evaluate constructors on controller and extensions"?

A developer wrote a Visualforce page for Sales Reps to add products to an order. The page takes a URL query parameter, productFamily, which filters the product results. The test method for the filter behavior has an assertion failing due to an incorrect number of results.
Why could the test be failing? (Choose two.)

A developer wrote an Apex method that makes an HTTP callout to an external system to get specialized data when a button is clicked from a custom Lightning web component on the Account record page.
Recently, users have complained that it takes longer than desired for the data to appear on the page after clicking the button.
What should the developer use to troubleshoot this issue?

A Visualforce page contains an industry select list and displays a table of Accounts that have a matching value in their Industry field.

When a user changes the value in the industry select list, the table of Accounts should be automatically updated to show the Accounts associated with the selected industry.
What is the optimal way to implement this?
