You open a short program a classmate wrote. What should you do first?

• Say what it does before running it
• Rewrite it from scratch at once
• Run it ten times without reading

Someone wrote this line: if 3 = 4 then "yes" else "no". Without running it, what does it produce?

• "yes"
• 3
• "no"

Here is another short program:

if false then "yes" else "no"

What kind of value does it give back?

• A whole number
• A true or false value
• A piece of text
• It gives an error

Program: if true then 5 else 8. What kind of value does it give back?

• A true or false value
• A piece of text
• A whole number

Program: if score >= 50 then "pass" else "retry". The pass mark must rise from 50 to 60. Which part must change?

• The word then
• The test: score >= 50 to score >= 60
• The text "retry"

Read this program a classmate wrote:

if speed > 30 then "slow down" else "ok"

The limit must drop from 30 to 25. Which part of the line must change?

• The else answer: change "ok" to "fine"
• The then answer: change "slow down" to "stop"
• The test: change speed > 30 to speed > 25
• Nothing, the line already handles it

Read before running: if "cat" = "dog" then 1 else 0. What does it give back, and why?

• 1, because every if starts with the then answer
• 0, because the two words are not the same
• It breaks, because words cannot be compared

Read this program before running it:

if "sun" = "sun" then 1 else 0

What does it give back, and why?

• 0, because words cannot be compared
• 1, because the two words are the same
• 0, because the test is false
• It gives an error
