Question

alana and joey flashed wide smiles chock full of silver. “let’s just say we built on our assets,” alana said.
how were alana and joey able to create an app to help kids and orthodontists?

• they thought about the type of tool that would most impress the judges.
• they used their own experience to design something useful to others.
• they focused on the coding part to develop something safe and secure.
• they considered the activities that students like to do outside of school.

Explanation:

To solve this, we analyze each option:

• Option 1: The text doesn't mention impressing judges, so this is incorrect.
• Option 2: Alana and Joey have silver (braces) and "built on our assets" implies using their own experience (with orthodontic issues) to design a useful app, which matches.
• Option 3: The text doesn't focus on coding for safety/security, so incorrect.
• Option 4: The text doesn't mention outside - school activities, so incorrect.

Answer:

B. They used their own experience to design something useful to others.
