4. When drawing a dog, which of the following characteristics is non-essential?

• Dogs have 4 paws
• Dogs have excellent hearing.
• Dogs have a tail
• Dogs can run fast.

5. Why do we need to look for patterns in problems?

• Patterns make it easier for us to solve complex problems.
• Patterns make it harder for us to solve complex problems.
• Patterns can be used to break the problem down into smaller parts.
• When we find the patterns, we can ignore it to solve the problem.
