16. D

years to write TOEFL pattern: take + time + to do something

17. A

No none is a pronoun; no is a determiner.

Here is an easy sentence to memorize:

No two snowflakes are alike.

18. C

private We need the adjective form here to be parallel with the adjectives federal and local. All three adjectives modify the noun organizations.

19. A

an We need an because the next word begins with a vowel sound.

20. C

specially We need the adverb form here to modify the verb designed.

21. C

depends on The correct form is depend on x for y. For example:

I depend on my parents for support.

22. D

any any is a determiner. We cannot use a preposition between a determiner and a noun.

23. A

that what can only be used for noun clauses. We have an adjective clause here modifying the noun rays.

24. C

immensely powerful We need this order

adverb + adjective

since we want the adverb immensely to modify the adjective  powerful.

25. A

beauty We need the noun form here since we need a main subject.

26. B

is designed We need the singular form of the verb here to agree with the singular main subject Project.

27. B

composed We need passive voice here. Notice that if we use the -ing form, we would need an object.

28. D

its We need the singular pronoun to agree with its singular referent seed.

29. B

economic We need the adjective form here to be parallel with the adjectives cultural and social. All three adjectives modify the noun forces.

30. A

living Simple sentence: bacteria play role

living is the -ing form from an adjective clause:

bacteria which live in the soil...

If we do not change lived, we would have two verbs in the sentence.

31. B

that are called


which are called



We have a double verb in this sentence. We should make the extra verb part of an adjective clause.

32. D

hot We need an adjective here. heat is a noun.

33. C

campaigning We need the object of the preposition after. campaign is a noun, but we need to use the gerund form here because we need to show that Carrie Chapman Catt was doing the action.

34. B

conducts We need a subordinate verb here. conducting is not a verb.

35. C

with This is a preposition combination question--we simply have to memorize the combinations.

36. D

farming We need to use the -ing form here to show that the family is doing the action of farming. Incidentally, this is one of the funniest mistakes on the TOEFL--if we use the -ed form, that means that the family received the action. In other words, the family was planted in the soil, like corn or wheat!!

37. A

invention inventor is a person; invention is a thing. We are talking about the thing here.

38. C

sewing machines machine is a singular count noun with no determiner. Therefore, it is WRONG, WRONG, WRONG!!

39. A

Nitrogen We do not use the with elements.

40. B

as a small stream is a singular count noun with no determiner. Therefore, it is WRONG, WRONG, WRONG!! The determiner always goes at the beginning of the noun phrase. In this case we should put the determiner before the adjective small.
