This second gap fill test contains 25 multiple choice questions on the topic of relative clauses (adjective clauses) of English grammar. Both English learners and ESL teachers can use this online exercise as a revision to check the knowledge of English relative clauses (adjective clauses).
Question 1
The report from the hospital said a study following a group of 354 girls found those _____ were fatter at age 3 and _____ gained weight during the next three years reached puberty by age 9.
Both gaps are subject relative pronouns that refer to people (those = those girls). Who is the usual choice for people, and that is also possible in a defining clause, so those who were fatter … and that gained weight works. Which is not used for people, and whom cannot be the subject of gained.
Question 2
He is the man _____ we have heard so much.
The verb pattern is hear about someone: we have heard so much about him. In formal English the preposition moves in front of the relative pronoun, and after a preposition we use whom: the man about whom we have heard so much. Not plain whom, because the preposition about would then be missing.
Question 3
Dickens held the mirror up to nature and, of its reflected fragments, composed a fresh world, _____ the men and women differ from real people only in _____ they live in a literary medium.
The first gap refers to the place a fresh world, so it needs where (= in which): a fresh world, where the men and women differ …. The second gap completes the fixed conjunction in that, which means because or in the respect that: they differ only in that they live in a literary medium. Not which in the second gap: only in which they live has no noun for which to refer to, so it makes no sense.
Question 4
The great ship, _____ is called Titanic, sailed for New York from Southampton on April 10th, 1912.
This is a non-defining relative clause between commas, and it refers to a thing (the ship), so we use which. That cannot be used in non-defining clauses, and who is for people.
Question 5
It is often impossible to identify a 'cause' in many people and this can be distressing for people _____ want to understand the reasons _____ they are ill.
The first gap is the subject of want and refers to people, so it needs who (or that). Whom is an object form, and which is not used for people. After reason(s) the formal relative is for which, which means the same as why: the reasons for which they are ill = the reasons why they are ill. Not of which or in which, because we speak of a reason for something.
Question 6
Verrazzano, an Italian _____ little is known, sailed into New York Harbour in 1524 and named it Angoulême.
The pattern is know (little) about someone: little is known about him. In a formal relative clause the preposition comes before the pronoun, and after a preposition we use whom for a person: an Italian about whom little is known. Not whom alone, because the preposition about is needed.
Question 7
Even the Discovery Channel, _____ is set to air the controversial documentary on Sunday, March 4, seemed confused by Feuerverger’s calculations.
The clause between commas is non-defining and refers to a thing (the Discovery Channel, a company), and the pronoun is the subject of is set to air. So we need which. That is not used in non-defining clauses, and in which, where and when cannot be the subject of a verb.
Question 8
They haven’t got many interests _____ they share.
The relative pronoun is the object of share (they share interests) and refers to things, so which is correct. In a defining clause like this it could also be left out: interests they share. Not in which, because we share interests; we do not share in them here.
Question 9
Satisfaction is an emotion _____ captures the uniquely human need to impart meaning to one's activities.
The gap is the subject of captures and refers to a thing (an emotion), so a defining relative pronoun that (or which) is needed. Who and whom are for people, and in which or when cannot be the subject of a verb.
Question 10
Franklin was one of the “Founding Fathers,” the only one _____ put his name to some documents of the States _____ we still live.
The first gap refers to a person (the only one = Franklin) and is the subject of put, so who is used. The second gap refers to the States, where we live, so it needs a preposition + which: the States in which we still live (= where we still live). Not that or which alone, because live needs the preposition in.
Question 11
The writer gave full vent to his wit in his favourite form of literary composition, the hoax, _____ he pretended to be someone else.
The clause refers to the hoax, a form of writing. The writer pretended to be someone else in the hoax, so we need in which. Not which alone, because he pretended to be someone else is already a complete clause and needs the preposition. That cannot follow a comma in a non-defining clause.
Question 12
He conveyed to others in his lifetime a sense of _____ he was _____ made and makes him worth knowing just for himself.
The first gap starts a noun clause about identity: a sense of who he was (= his personality). The second gap is a defining relative pronoun referring back to a sense, and it is the subject of made and makes: a sense … that made and makes him worth knowing. Not how, because how he was would describe his health or condition, not his character.
Question 13
There is no writer, in my opinion, _____ is so much a painter and a black-and-white artist as Dickens.
The gap refers to writer (a person) and is the subject of is, so we need a subject relative pronoun. That is common after negative or general words like no writer, nobody, the only. Whom is an object form, and whose would need a noun after it.
Question 14
Keats's letters reveal the sense of enjoyment _____ he wrote, and reflect the active searching of a youthful and ever-developing mind.
The collocation is write with enjoyment: he wrote with enjoyment. In a formal relative clause the preposition goes before the pronoun: the sense of enjoyment with which he wrote. Not which or that alone, because wrote needs the preposition with here.
Question 15
Companies in countries _____ use historical cost accounting — recording only the original purchase price of assets — do not usually record an estimated market value — the price at which something could be sold today.
The gap is the subject of use and refers to countries (things), so we need which. Not where: where is an adverb and cannot be the subject of a verb. Compare countries where companies use … with countries which use ….
Question 16
Hamlet reveals his personal perceptions of the events _____ take place in his homeland and _____ are either indirectly or directly tied to his father’s murder.
Both gaps are subject relative pronouns referring to the events (things): events that take place … and which are … tied to his father's murder. That and which are both possible in defining clauses. Who is only for people, and where cannot be the subject of take place.
Question 17
There are few companies _____ can deliver an end-to-end customised solution specific to a healthcare environment, _____ is what the owners have done.
The first gap is a defining relative pronoun referring to companies and acting as subject of can deliver, so that works. The second gap refers to the whole idea before it (delivering such a solution), and this needs a comma + which: …, which is what the owners have done. Not what: what already contains its own noun (= the thing that), so it cannot refer back to a previous clause.
Question 18
In a world _____ obesity is becoming one of the most frequent issues, studies show that high consumption of cholesterol is harmful.
A world is treated as a place, and the clause after it is complete (obesity is becoming … has its own subject), so we need the relative adverb where (= in which). Not which or that: they would have to be the subject or object of the clause, but the clause already has both.
Question 19
The tablet tells the story of an ancient king of Uruk _____ may have actually existed, and _____ name is on the Sumerian King List.
The first gap refers to a person (a king) and is the subject of may have existed, so we use who. The second gap shows possession before a noun (his name), so we use whose: and whose name is on the Sumerian King List. Not of which: it is used for things and cannot come directly before name like this.
Question 20
Formerly a halt on the caravan route between the Aegean and Konya, Afyon remains an important junction _____ cereals are brought for onward shipment.
The verb pattern is bring something to a place: cereals are brought to the junction. In a formal relative clause the preposition moves before the pronoun: a junction to which cereals are brought (= where cereals are brought). Not whose, because there is no possession: the cereals do not belong to the junction.
Question 21
The retina converts the light rays into impulses _____ are sent to the brain, _____ they are recognized as images.
The first gap is a defining relative pronoun referring to impulses and acting as subject of are sent, so that fits. The second gap refers to a place (the brain) and introduces a complete clause (they are recognized as images), so we need where. Not when, because the brain is a place, not a time.
Question 22
Acne is a very common skin disorder _____ most young people get in early puberty.
The pronoun is the object of get (young people get the disorder) and refers to a thing, so that (or which, or no pronoun) is correct. Not in which or where, because nobody gets something in a disorder; the disorder itself is what they get.
Question 23
It is only your own actions _____ you may take responsibility and credit.
The collocations are take responsibility for and take credit for something. In formal English the preposition goes before the relative pronoun: actions for which you may take responsibility and credit. Not that alone, because for would then be missing; you would have to say that you may take responsibility and credit for.
Question 24
Nash is the attorney _____ John Fitzgerald counts as his firm’s top malpractice litigator and the lawyer who, Fitzgerald himself says, would be “the last person in the world he’d want to try a case against.”
The pattern is count someone as something: Fitzgerald counts him as his firm’s top litigator. The relative pronoun replaces him, the object of counts, so the formal object form whom is correct. Not whose, because there is no noun after the gap to show possession, and which is not used for people.
Question 25
Start with a free walking tour in the centre, _____ you’ll be impressed by the scale of the huge central plaza.
The clause refers to a place (the centre) and is complete on its own (you’ll be impressed … has a subject and verb), so the relative adverb where is needed. Not which, because which would need to be the subject or object of the clause, and that clause already has both.
