Question 1

Istanbul is a city _____ you can literally see growing bigger and bigger with each year.

The gap starts a defining relative clause about a city, and the pronoun is the object of see (you can see the city growing). For a thing as object, use which (or that). Not where: where replaces a place adverbial, but the clause already has a missing object, not a missing 'in it'.

Question 2

Every month the queues at the traffic lights on the way to Istanbul get longer and longer, _____ is extremely frustrating, and people can’t help wondering what it is going to be like ten years from now.

After a comma, which can refer back to a whole clause: the fact that the queues get longer is extremely frustrating. That cannot follow a comma in a non-defining clause, and what cannot refer back to a previous idea.

Question 3

The World Cup fans applauded a police officer, _____ had pushed his way through the crowd to return a lost child to her parents.

The clause adds extra information about a person, a police officer, and the pronoun is the subject of had pushed, so we use who. Not that: that cannot be used after a comma in a non-defining relative clause.

Question 4

The River Danube, _____ flows through Germany, Hungary, Austria, Serbia, Romania and borders Slovakia, Croatia, Bulgaria and Ukraine, is the longest and the most important river in Central Europe.

This is a non-defining clause (between commas) about a thing, the River Danube, and the pronoun is the subject of flows. Use which. Not that: it is not used in non-defining clauses after a comma.

Question 5

From the Black Forest, _____ it rises, the Danube flows a distance of 2,850 kilometres to the Black Sea.

The clause means 'the Danube rises in the Black Forest', so we need a relative adverb of place: where (= in which). Not which: it rises which has no preposition, so it needs in which or where.

Question 6

During the World Cup, dozens of officers patrolled the main avenues of Paris, _____ cafes overflowed with football fans.

The clause means 'cafes overflowed with fans in Paris'; the clause already has a subject (cafes), so we need where (= in which). Not which: which would need a missing subject or object in the clause.

Question 7

My brother John, one of _____ strongest fears when he was young was of heights, surprisingly, became a pilot.

The meaning is 'one of his strongest fears', so we need the possessive relative whose: one of whose strongest fears. Whose is followed directly by a noun (fears).

Question 8

The chief advisor, by _____ the president had been betrayed, had ambitions of becoming the president himself.

After a preposition (by) referring to a person, we use whom: the president had been betrayed by him → by whom. Not which (for things) and never that directly after a preposition.

Question 9

_____ like the Greek letter “omega”, Coffin Spring is nothing new in orthodontics.

This is a reduced participle clause with a passive meaning: the Coffin Spring is shaped like an omega. A passive meaning needs the past participle Shaped. Not Shaping: that would mean the spring shapes something itself.

Question 10

Hawaii’s soil, _____ is composed of volcanic lava, ash and sandy stone, is so fertile that it yields eleven tons of sugar per acre, _____ is the largest yield on Earth.

Both gaps follow a comma, so both clauses are non-defining. The first which refers to Hawaii's soil (subject of is composed); the second which refers to the whole idea 'eleven tons of sugar per acre'. That cannot be used after a comma in this way.

Question 11

The clause means 'people chop their own wood in New England'. It already has a subject and object, so we need where (= in which). Not which: there is no missing subject or object for it to replace.

Question 12

Students _____ haven’t yet collected their student identification cards are reminded that they have to do so before the end of the month.

This defining clause tells us which students, and the pronoun is the subject of haven't collected. For people as subject, use who (or that). Not whose: it needs a noun after it.

Question 13

The heart, _____ main function is to pump blood around the body, is greatly affected by the food we eat.

The meaning is 'its main function', so we need the possessive whose, followed by the noun main function. Whose can be used for things as well as people. Not which: which main function does not show possession.

Question 14

The original inhabitants of Hawaii were probably Polynesians, _____ sailed from the islands of South East Asia, perhaps as early as 400 AD.

The clause adds information about people, Polynesians, and the pronoun is the subject of sailed, so we use who. Not whose: it must be followed by a noun.

The clause ends with the preposition in (enrolled in the school), so we need an object pronoun: that (or which). Not where: where already means 'in which', so where he's enrolled in would repeat the preposition.

The meaning is 'I am familiar with his (Dickens's) work', so we need the possessive whose + noun (work) after the preposition: with whose work. Not whom: it cannot be followed by a noun.

One of the most controversial issues _____ lately is whether people _____ from minor illnesses should be allowed to work from home.

Both gaps are reduced relative clauses. The issues have been discussed (passive) → past participle discussed. The people are suffering from illnesses (active) → present participle suffering. Not being discussed / to suffer: to suffer cannot replace a relative clause here.

First gap: a defining clause with the object pronoun left out: the people (whom) the police questioned, so it needs a finite verb, questioned.
