Q1  20
Q1 20

Question 1: The opposite of 'happy' is ___.

Question 1 options
'Unhappy' is correct because the prefix 'un-' is added to adjectives to mean 'not' or 'the opposite of.' 'Dishappy' is wrong because 'dis-' does not combine with 'happy.' 'Inhappy' and 'imhappy' are not real English words.
Q2 20

Question 2: She is a good ___. She sings very well.

Question 2 options
'Singer' is correct because the suffix '-er' is added to the verb 'sing' to form a noun meaning 'a person who sings.' 'Singful,' 'singment,' and 'singly' are not standard English words.
Q3 20

Question 3: I need to ___ my homework because it has too many mistakes.

Question 3 options
'Redo' is correct because the prefix 're-' means 'again.' Adding 're-' to 'do' creates the meaning 'do again.'
Q4 20

Question 4: Be ___! There is ice on the road.

Question 4 options
'Careful' is correct because the suffix '-ful' is added to the noun 'care' to form an adjective meaning 'full of care' or 'cautious.' 'Careble,' 'careish,' and 'carement' are not real English words.
Q5 20

Question 5: The prefix 'un-' means 'not' or 'the opposite of,' as in 'unfair' and 'unkind.'

Question 5 options
True because 'un-' is one of the most common English prefixes and it reverses the meaning of the base word. 'Unfair' means 'not fair' and 'unkind' means 'not kind.'
Q6 20

Question 6: Adding the suffix '-ness' to the adjective 'kind' creates the noun ___.

Question 6 options
'Kindness' is correct because the suffix '-ness' converts adjectives into nouns that describe a quality or state. 'Kindly' is an adverb formed with '-ly.' 'Kinder' is a comparative adjective. 'Kindful' is not a standard English word.
Q7 20

Question 7: Which word uses the prefix 'mis-' to mean 'wrongly'?

Question 7 options
'Misunderstand' is correct because the prefix 'mis-' means 'wrongly' or 'badly,' so 'misunderstand' means 'to understand wrongly.' 'Disappear' uses 'dis-,' 'unlock' uses 'un-,' and 'preview' uses 'pre-.'
Q8 20

Question 8: Match each prefix to its meaning.

Question 8 options
pre-
dis-
over-
sub-
under / below
too much
not / opposite
before

Select an item on the left, then tap its match on the right.

'Pre-' means 'before,' 'dis-' means 'not/opposite,' 'over-' means 'too much,' and 'sub-' means 'under/below.'
Q9 20

Question 9: The children were very ___ during the trip. They never stopped talking!

Question 9 options
'Talkative' is correct because the suffix '-ative' turns the verb 'talk' into an adjective describing someone who talks a lot. 'Talky' is informal and rare. 'Talkness' and 'talkment' are not standard English words.
Q10 20

Question 10: We need to ___ the old building before constructing a new one.

Question 10 options
'Demolish' is correct. However, this question tests the prefix 'de-,' which can mean 'remove' or 'reverse.' 'Demolish' means to completely destroy a structure. 'Premolish,' 'remolish,' and 'unmolish' are not real English words.
Q11 20

Question 11: That story is hard to believe. It sounds completely ___.

Question 11 options
'Unbelievable' is correct because the prefix 'un-' (meaning 'not') and the suffix '-able' (meaning 'able to be') combine with 'believe' to form an adjective meaning 'not able to be believed.'
Q12 20

Question 12: The suffix '-less' in 'careless' indicates that someone is ___.

Question 12 options
'Without care' is correct because the suffix '-less' means 'without' or 'lacking.' A careless person lacks care or attention. 'Full of care' is the meaning of '-ful.' 'Before care' would relate to 'pre-.' 'Against care' would relate to 'anti-.'
Q13 20

Question 13: The prefix 'im-' is used before words starting with 'p' or 'm' instead of 'in-,' as in 'impossible' and 'immature.'

Question 13 options
True because 'in-' changes to 'im-' before the letters 'p,' 'b,' and 'm' for easier pronunciation. 'Impossible' (not 'inpossible') and 'immature' (not 'inmature') follow this rule.
Q14 20

Question 14: The doctor told her that eating too much sugar is ___.

Question 14 options
'Unhealthy' is correct because the prefix 'un-' added to the adjective 'healthy' creates the opposite meaning. 'Dishealthy,' 'inhealthy,' and 'mishealthy' are not standard English formations.
Q15 20

Question 15: Which word correctly uses the suffix '-tion' to form a noun from the verb 'communicate'?

Question 15 options
'Communication' is correct because when verbs ending in '-ate' take the suffix '-tion,' the '-ate' is replaced and '-ation' is added. 'Communicatement,' 'communicateness,' and 'communicately' use incorrect suffixes for this verb.
Q16 20

Question 16: Put these word parts in the correct order to form the word meaning 'not able to be replaced':

Question 16 options
  • -able
  • replace
  • ir-

Drag items or use arrows to arrange them in the correct order.

The correct order is 'ir- + replace + -able' → 'irreplaceable.' The prefix 'ir-' (a variant of 'in-' before 'r') means 'not,' the root is 'replace,' and the suffix '-able' means 'able to be.'
Q17 20

Question 17: The company decided to ___ several employees due to budget cuts, meaning they had to reduce the workforce.

Question 17 options
'Downsize' is correct because the prefix 'down-' combined with 'size' means to reduce in size or number. 'Upsize' means to increase. 'Resize' means to change size generally. 'Oversize' is an adjective meaning too large.
Q18 20

Question 18: When the final 'e' is dropped before adding a suffix, which of the following is correctly spelled?

Question 18 options
'Lovable' is correct because when a word ends in a silent 'e' and the suffix begins with a vowel (like '-able'), the 'e' is typically dropped. 'Loveable' is sometimes accepted but 'lovable' is the standard spelling. 'Hopeing' should be 'hoping,' 'makeing' should be 'making,' and 'writeing' should be 'writing.'
Q19 20

Question 19: The politician's speech was full of anti-government ideas. The prefix 'anti-' means ___.

Question 19 options
'Against' is correct because the prefix 'anti-' comes from Greek and means 'against' or 'opposed to.' Anti-government means opposed to the government.
Q20 20

Question 20: The researcher found the results to be ___, meaning they could not be produced again in another experiment.

Question 20 options
'Irreproducible' is correct because the prefix 'ir-' (variant of 'in-' before 'r') means 'not,' combined with 'reproducible' (able to be reproduced). 'Unreproducible' uses the wrong negative prefix for words starting with 'r.' 'Disreproducible' and 'misreproducible' use prefixes that do not combine with 'reproducible.'
