Answer 2

In a flowchart, an arrow starts from an oval labeled “Start” and ends at a parallelogram “Input username.” From the parallelogram labeled “Input username,” an arrow starts and ends at a parallelogram labeled “Scan fingerprint.” An arrow starts from the parallelogram labeled “Scan finger print” and ends at a diamond labeled “Username and scan correct?” From the diamond, two arrows are originated. One from the right corner, labeled “No” and one from the bottom corner, labeled “Yes.” The arrow labeled “No” ends at a diamond labeled “Is this the third attempt?” From the diamond, “Is this the third attempt?” two arrows are originated. One from the top corner, labeled “No” and one from the bottom corner. The arrow labeled “No” ends at an oval labeled “Start.” Another arrow from bottom ends at an oval labeled “Stop.” The arrow labeled “Yes” from the bottom of the diamond labeled “Username and scan correct?” ends at a rectangle labeled “Access to the system given.” An arrow originated from the rectangle labeled “Access to the system given” and ends at an oval labeled “Stop.”

Answer 3

Which input would display “Full price ticket”?
In a flowchart, an arrow starts from an oval labeled “Start” and ends at a parallelogram labeled “Input Age”. From a parallelogram labeled “Input Age”, an arrow starts and ends at a diamond labeled “Age 16 or under”. Two arrows start from diamond labeled “Age 16 or under”. One from the right corner, labeled “Yes” and one from the bottom corner, labeled “No”. The arrow labeled “Yes”, ends at a rectangle, labeled “Half-price ticket”. The arrow labeled “No” ends at another diamond labeled “Age 60 or above”. From diamond labeled “Age 60 or above”, two arrows are originated. One from the right corner labeled “Yes” and one from the bottom corner labeled “No”. The arrow labeled “Yes”, ends at a rectangle, labeled “Half-price ticket”. The arrow labeled “No”, ends at a rectangle labeled, “Full price ticket”. An arrow starts from the rectangle “Full price ticket” and ends at an oval labeled “Stop”. Similarly, an arrow starts from the rectangle “Half-price ticket” and ends at an oval labeled “Stop”.

Answer 4

The symbol that is always required in every flowchart is the **terminal** symbol. This symbol represents the start and end of a flowchart.

Answer 5

If an algorithm behaves differently for adults and children, the appropriate symbol to use in the flowchart is the **decision** symbol. This symbol is used to represent a point in the algorithm where a decision needs to be made, leading to different branches based on the outcome.

Answer 6

Based on the description of the flowchart, the elements that appear to be critical to the decision-making process relate to what is being verified at different points. The two main factors considered in the flowchart are the **username** and **fingerprint**.

Thus, the appropriate response would be **username and fingerprint**.

Answer 7

In the flowchart described, the output “Full price ticket” is reached when the age input does not meet the criteria for half-price. Specifically:

- If the age is **16 or under**, it leads to a “Half-price ticket.”
- If the age is **60 or above**, it also leads to a “Half-price ticket.”
- For ages **between 17 and 59**, which would include the age **20**, it leads to a “Full price ticket.”

Given these conditions, the correct input that would display “Full price ticket” is **20**.
