Describe the role of event handlers in Block Coding within MIT App Inventor.

• Event handlers are used for debugging errors in MIT App Inventor

• Event handlers are responsible for compiling code in MIT App Inventor

• Event handlers are used for designing user interfaces in MIT App Inventor

• Event handlers in Block Coding within MIT App Inventor are blocks of code that respond to specific events triggered by user interactions or system events.

What is the significance of the 'Designer' and 'Blocks' sections in MIT App Inventor?

• The 'Designer' section is for testing the app, and the 'Blocks' section is for sharing the app.

• The 'Designer' section is for importing assets, and the 'Blocks' section is for exporting the project.

• The 'Designer' section is for writing code, and the 'Blocks' section is for designing the user interface.

• The 'Designer' section is for designing the user interface, and the 'Blocks' section is for programming the functionality of the app.

How can you create a button that changes color when clicked in MIT App Inventor?

• Set the button's color property to change randomly on each click.

• Use the 'Hover' event block to change the button's color property.

• Use the 'Click' event block to change the button's color property to a different color.

• Create a new button each time the current button is clicked.

Explain the difference between 'Screen Arrangement' and 'Layout' in User Interface Design.

• Screen Arrangement focuses on color schemes, while Layout deals with font choices.

• Screen Arrangement deals with the positioning of elements, while Layout focuses on the overall structure and organization of elements.

• Screen Arrangement involves user interactions, while Layout involves backend coding.

• Screen Arrangement refers to the size of the screen, while Layout refers to the animation effects.

What are some advantages of using MIT App Inventor for mobile app development?

• User-friendly, no coding experience required, visual interface, real-time testing, large community support

• Limited functionality

• Requires advanced coding skills

• Slow performance

How can you use variables in Block Coding to store and manipulate data?

• By assigning values to variables and using them in blocks that perform operations or calculations.

• By ignoring variables and directly inputting data in blocks

• By deleting variables after assigning values

• By using variables to create animations
