 ## 2. What is JavaScript?
 
-An exciting new play about coffee.
+A programming language that makes websites etc. more dynamic: for example, enabling user interaction &/or animating objects. It works in conjunction with HTML (structure and content) and CSS (style).
+
+JavaScript is an interpreted language, so it is executed in a user's browser rather than being processed by the server first.
 
 ## 3. Name three problems Git & GitHub solve?
 
-When people want to show off code to each other they can put it on GitHub
+Git software enables developers to create and manage versions of a project. 
+
+GitHub provides a platform for developers to work on these projects together, simultaneously, and to share them with others. 
+
+By doing so, they solve the following problems:
+
+1. Not being able to work on the same project simultaneously
+2. Not having a clear history of how a project developed, including knowing who was responsible for particular changes
+3. Not having an easy system to review changes and agree what should be taken forward
 
 ## 4. What happens when you `fork` a repository?
 
-You delete it
+You make a copy of it, adding this copy to your own profile as a new repository. Unless you change it, this copy will still keep the original repository as its 'upstream' source. 
 
 ## 5. What happens when you clone a repository?
 
-It send it to a friend
+You make a local copy.
 
 ## 6. What is a Pull Request?
 
-When you send a file over the internet
+When you request to merge a particular 'commit' or version of the project into the main branch - which essentially makes that version the latest/main one.
