Spot the Error

Question 1
A ui ← "how a screen looks"
B ux ← "how it feels to use"
C good_ux ← pretty AND colourful
Line C — Good UX is about how easy and pleasant a system is to use, not just how it looks. It should be good_ux ← easy AND pleasant.
Question 2
A ux ← "only the colours"
B ui ← "the look of the screen"
C PRINT "UX is more than UI"
Line A — UX is the whole experience from start to finish, not only the colours. Line 1 should describe the whole journey of use.
Question 3
A annoyed ← 0
B IF page loads quickly THEN
C annoyed ← annoyed + 1
Line B — A slow page is a frustration point that makes users more annoyed. A quick page is not a problem, so line 2 should say slowly.
Question 4
A steps_old ← 9
B steps_new ← 3
C fewer ← steps_new < steps_old
D IF fewer THEN easier ← FALSE
Line D — Fewer steps make a system easier to use. So when fewer is true, easier should be set to TRUE.
Question 5
A font_size ← "UI"
B button_colour ← "UI"
C time_to_finish ← "UX"
D logo_shape ← "UX"
Line D — The shape of a logo is about how the interface looks, so it is UI. Time to finish a task is a UX measure.
