For each question, choose the correct answer.
Coral Reefs Under the Sea
Coral reefs are beautiful places under the sea. You can usually find them where the water is warm and shallow. They cannot grow in deep water (19)…………… they need a lot of sunlight to live.
Many people think coral reefs are just rocks, but tiny sea animals actually make them. Over thousands of years, millions of these animals build a big reef together. These reefs become very important (20)…………… for ocean life.
In fact, thousands of different kinds of (21)…………… sea plants and fish live there. Many ocean animals visit the reefs every day to (22)…………… for food. It is also a good place for small fish. They like to (23)…………… inside the reef so that bigger fish cannot catch them. Because coral reefs are so special, we must do our best to (24)…………… them safe.
19 A because B so C but
20 A homes B houses C buildings
21 A colourful B kind C happy
22 A look B watch C see
23 A hide B lose C miss
24 A keep B put C let
Answer Key & Explanations
19 A (because): We use the conjunction 'because' to give the reason why reefs cannot grow in deep water (they need sunlight). 'So' would introduce a result, and 'but' shows a contrast, neither of which fits the logic of this sentence.
20 A (homes): The natural environment where an animal lives is its 'home'. We use 'houses' and 'buildings' for places that humans construct to live or work in, not for natural animal habitats.
21 A (colourful): 'Colourful' describes the physical appearance of the bright plants and fish on the reef. 'Kind' and 'happy' are adjectives used to describe the feelings or personalities of people and pets, not wild sea life.
22 A (look): The verb 'look' naturally collocates with the preposition 'for' (look for) to mean searching. We do not say "watch for food" or "see for food" when talking about an animal actively trying to find something to eat.
23 A (hide): The broader context explains that small fish do this so bigger fish "cannot catch them". 'Hide' means to stay out of sight, which fits perfectly. You cannot 'lose' or 'miss' yourself inside a reef to stay safe.
24 A (keep): The phrase "keep safe" is a standard English collocation meaning to protect something. We do not use 'put' or 'let' with the adjective 'safe' in this way.

Questions 19-24
For each question, choose the correct answer.
How Caves are Formed
Caves are amazing places that you can find under the ground all over the world. They are usually completely (19)…………… inside because light from the sun cannot reach them. Explorers love to visit them, but they always carry a lamp.
Most caves take a very long time to form. It usually happens when rain falls on the ground. Under the earth, this water moves through the soft stone and slowly (20)…………… a hole. After a million years, this hole becomes a large cave.
Inside, you can often see beautiful shapes hanging from the top. They look (21)…………… long teeth made of ice, but they are actually solid (22)…………… . If you visit a cave, it is a good (23)…………… to go with a guide. A guide knows the paths well and will keep you (24)…………… .
19 A dark B black C blind
20 A makes B does C puts
21 A like B as C same
22 A rock B earth C sand
23 A idea B plan C answer
24 A safe B sure C true
Answer Key & Explanations
19 A (dark): 'Dark' is the correct semantic fit to describe a place with no light. 'Black' is a specific colour, and 'blind' describes a person or animal that cannot see.
20 A (makes): 'Make a hole' is a strong, natural collocation in English. 'Does' and 'puts' do not form a meaningful phrase with 'a hole'.
21 A (like): 'Look like' is a fixed phrase-level structure used to say that two things have a similar appearance. 'As' and 'same' do not fit this grammatical structure.
22 A (rock): 'Rock' is the correct semantic fit for hard, solid stone found in caves. 'Earth' means dirt or soil, and 'sand' is made of loose grains; neither of these could hang solidly from a ceiling.
23 A (idea): 'A good idea' is a common English collocation used when giving advice. 'Plan' and 'answer' do not form a natural phrase in this specific sentence structure.
24 A (safe): In this broader context, knowing the paths helps the guide protect you so you do not get lost, keeping you 'safe'. 'Sure' means certain, and 'true' means a correct fact; neither makes sense here.

Questions 19-24
For each question, choose the correct answer.
Amazing Waterfalls
Waterfalls are some of the most beautiful sights in the world. They happen when a river flows from a very (19)…………… place and falls down quickly into a pool at the bottom.
Because a large (20)…………… of water is moving so fast, waterfalls are usually very (21)…………… . In fact, you can often hear them from a long way away!
When people visit famous waterfalls, they usually love to (22)…………… photos of the beautiful views. Visitors often use small boats to travel close to the falling water. If you go on one of these boats, you should wear a raincoat because you will probably (23)…………… quite wet. Waterfalls truly are a wonderful (24)…………… of the natural world, and they are always exciting to see.
19 A high B tall C deep
20 A amount B number C size
21 A noisy B upset C heavy
22 A take B make C catch
23 A get B have C make
24 A part B piece C member
Answer Key & Explanations
19 A (high): This tests semantic fit. "High" describes places or land far above the ground. "Tall" is usually used for upright objects like people, trees, or buildings, and "deep" measures distance below the surface.
20 A (amount): This tests phrase-level meaning and grammar. The phrase "a large amount of" is used with uncountable nouns like water. "Number" is only used for countable nouns (e.g., a number of rivers), and "size" does not fit this specific phrase structure.
21 A (noisy): This tests broader context. The following sentence states that you can "hear them from a long way away." This context clue makes "noisy" the only logical choice. "Upset" describes feelings, and "heavy" relates to weight.
22 A (take): This tests a highly frequent collocation. In English, the correct verb to use with "photos" or "pictures" is always "take", never "make" or "catch".
23 A (get): This tests a common A2 collocation. We use the verb "get" followed by an adjective (like wet, tired, or cold) to describe a change in condition or state. We do not use "have" or "make" in this structure.
24 A (part): This tests semantic fit. "Part of the natural world" is a standard way to describe something that belongs to a larger whole. "Member" is used for people or animals belonging to a group, and "piece" is used for physical objects (e.g., a piece of cake).
