Straight from the PrepMojo question bank, written to the pattern of the SOF papers. Have a go, then open the answer.

1. Question 1 · English

   Complete the idiom: "once in a blue ____".

   1. A.day
   2. B.moon
   3. C.sea
   4. D.sky
   Show answer

   Answer: B. moon

   The idiom is "once in a blue moon", and it means something that happens very rarely. An idiom keeps the very same words every time it is used, so an ending that only fits the sense is still the wrong one.

2. Question 2 · English

   They ___ jumping now.

   1. A.Are
   2. B.Am
   3. C.Was
   4. D.Is
   Show answer

   Answer: A. Are

   We say: They are jumping now. 'Was' would mean it already happened - the sentence says now.

3. Question 3 · English

   Which spelling is correct for 'a coloured rubber bag you fill with air'?

   1. A.Balloon
   2. B.Ballon
   3. C.Balloone
   4. D.Baloon
   Show answer

   Answer: A. Balloon

   'Balloon' is spelled correctly - it means a coloured rubber bag you fill with air. 'Baloon' is a common mistake: the double 'l' is often written as one.

4. Question 4 · English

   Which word is the opposite of 'bigger'?

   1. A.smaller
   2. B.smallest
   3. C.small
   4. D.biggest
   Show answer

   Answer: A. smaller

   The opposite of big is small, and the -er ending has to come across with it: bigger → smaller. Plain small is the right word at the wrong degree.

5. Question 5 · English

   Read this and answer the question. NOTICE The school library will stay shut on Friday. The shelves are being cleaned. Please return all borrowed books on Thursday. The library opens again on Monday. Mrs Rao, Librarian Why will the library stay shut?

   1. A.It is a holiday
   2. B.Mrs Rao is away
   3. C.There are no books left
   4. D.The shelves are being cleaned
   Show answer

   Answer: D. The shelves are being cleaned

   The passage says so directly: the shelves are being cleaned.

6. Question 6 · English

   A word is missing from this saying: "____ always pays." Which word is it?

   1. A.Honesty
   2. B.Lying
   3. C.Gold
   4. D.Politeness
   Show answer

   Answer: A. Honesty

   The saying goes "Honesty always pays." It teaches that a truthful child is trusted, and that trust is the reward. The missing word names a quality, which is why a thing you can hold never completes one of these sayings.

7. Question 7 · English

   Read the sentence: Joy plays with a round ball. Which word is the describing word?

   1. A.Ball
   2. B.Joy
   3. C.Plays
   4. D.Round
   Show answer

   Answer: D. Round

   'Round' is the describing word - it tells what kind. 'Ball' is often picked, but ball is the naming word the describing word tells about.

8. Question 8 · English

   3. C.Ravi rode to the shop
   4. D.The man mended the cycle
