✍️ Sample OC Questions & Answers
1. Which sentence has correct subject-verb agreement?
✓ The group of children is very noisy.
'Group' is the singular subject, so it takes the singular verb 'is'.
2. Which word is spelled correctly?
✓ accommodate
'Accommodate' is the correct spelling, with double 'c' and double 'm'.
3. A car park has 3 levels with 40 spaces on each level. On Monday morning, ¾ of spaces are taken. How many spaces are free?
✓ 30
Total spaces = 120; ¾ × 120 = 90 taken; 120 − 90 = 30 free spaces.
4. A clock shows 3:45. What angle do the minute and hour hands make?
✓ 157.5°
At 3:45 the minute hand is at 270° and the hour hand is at 3×30 + 45×0.5 = 112.5°; difference = 270 − 112.5 = 157.5°.
5. Which statement about all squares is true?
✓ All squares are rectangles
A square has all the properties of a rectangle (four right angles, opposite sides equal), so all squares are rectangles.
6. What is the meaning of "chronological order"?
✓ Order in which events happened in time
Chronological order arranges events in the sequence they occurred in time.
