Practice reading and repairing beginner-friendly pseudocode. Identify how IF, THEN, ELSE, and END IF organize instructions, spot syntax mistakes, and explain why precise structure matters.

Read the pseudocode.

IF batteryIsLow THEN
    showWarning
ELSE
    continueGame
END IF

When does continueGame run?

Both when the condition is true and false

Before the condition is checked

When batteryIsLow is false

Whenever batteryIsLow is true

A student wants the program to show `Access granted` if `hasPass` is true, and `Ask for a pass` otherwise. Which pseudocode has the correct structure?

IF hasPass ELSE / show Access granted / THEN / show Ask for a pass / END IF

IF hasPass THEN / ELSE / show Access granted / show Ask for a pass / END IF

IF THEN hasPass / show Access granted / ELSE / show Ask for a pass

IF hasPass THEN / show Access granted / ELSE / show Ask for a pass / END IF

Fix the syntax mistake in this pseudocode by changing only the keyword order:

IF THEN score >= 10
    showSuccess
END IF

Write the corrected first line.

A program contains this line:

IF doorIsOpen THEN ringBell

In the pseudocode convention used in this activity, a conditional must have separate indented action lines and end with END IF. What is the best fix?

IF doorIsOpen / indented THEN ringBell / END IF

IF doorIsOpen THEN / indented ringBell / END IF

THEN doorIsOpen IF / indented ringBell / END IF

IF doorIsOpen THEN / END IF / indented ringBell

A classmate says, “If a program’s instructions are understandable to a person, exact syntax does not matter.” Explain why proper syntax still matters, and distinguish a syntax mistake from a logic mistake.

Which sequence correctly shows the structure of a conditional in this activity’s pseudocode convention?

Condition, IF, action, ELSE, THEN

IF, condition, THEN, action, END IF

IF, action, condition, THEN, END IF

IF, THEN, condition, END IF, action

Read the pseudocode.

IF hasTicket THEN
    enterEvent
ELSE
    waitOutside
END IF

Which action runs when hasTicket is true?

Neither action runs

Both actions run

waitOutside

enterEvent

This conditional is missing a required keyword in the activity’s pseudocode convention:

IF isRaining THEN
    bringUmbrella

Which line should be added to complete the structure?

THEN after bringUmbrella

A second IF after bringUmbrella

END IF after bringUmbrella

ELSE before IF isRaining
