Question 1
A student wants to express the following idea: 'Watching TV late is bad for students. That is why they feel tired in the morning.'
Which single sentence using one of the target connectors (because, so, but) BEST combines these two ideas while maintaining the original logical relationship between them?
- Watching TV late is bad for students, so they feel tired in the morning. (correct answer)
- Watching TV late is bad for students because they feel tired in the morning.
- Students feel tired in the morning, but watching TV late is bad for them.
- Students feel tired in the morning because it is bad to watch TV late for them.
Explanation: When combining two sentences with connectors like because, so, and but, your first job is to identify the logical relationship between the ideas. Here, the original sentences show a cause-and-effect relationship: watching TV late is the cause, and feeling tired in the morning is the effect. That "That is why..." phrasing is your key signal — it points forward from cause to result.
The connector so introduces a result or consequence, making it perfect here. Option A reads: "Watching TV late is bad for students, so they feel tired in the morning." This preserves the original order — cause first, effect second — and uses so to signal that the tiredness results from the late TV watching. This is the correct answer.
Option B flips the logic entirely. Using because reverses the relationship, implying that students feel tired therefore watching TV is bad — but that's not what the original says. The cause and effect are inverted. Option C uses but, which signals contrast or contradiction. There's no contrast between these two ideas; one leads to the other, so but is the wrong connector. Option D also uses because, but beyond the same cause-effect reversal problem as B, the phrasing "it is bad to watch TV late for them" is awkward and unclear compared to the original.
A useful strategy: before picking a connector, ask yourself "Is this a cause→effect, a contrast, or a reason?" Then match: so = result, because = reason/explanation, but = contrast. Getting this mapping right will help you avoid common traps on connector questions.
Question 2
Read this student paragraph:
'I believe that learning English is very important for Ukrainian students. [BLANK] it opens many career opportunities abroad. English is difficult to master, [BLANK] students should not give up and must practise every day.'
Which pair of connectors correctly fills both blanks, preserving the student's intent to first support the opinion with a reason and then encourage persistence despite a challenge?
- But / because — the first connector contrasts English being important with career opportunities; the second gives a reason why students should not give up
- So / but — the first connector introduces career opportunities as a result of English being important; the second contrasts difficulty with the encouragement to persist
- Because / so — the first connector introduces the reason for English being important; the second shows that the difficulty leads to the recommendation not to give up (correct answer)
- Because / but — the first connector introduces the reason correctly, but the second introduces a simple contrast rather than showing that the difficulty causes the need to persist
Explanation: When filling in connectors, always ask yourself two questions: What is the logical relationship between these two ideas? and Does this connector express that relationship? The passage has two distinct jobs to do — first, support the claim that English is important by giving a reason, and second, acknowledge that English is difficult while still encouraging students to persist.
For the first blank, the sentence that follows ("it opens many career opportunities abroad") explains why English is important — it is a reason, not a result. The connector you need is one that introduces a cause or justification. "Because" does exactly this: "I believe learning English is important because it opens opportunities." For the second blank, the sentence acknowledges difficulty but pivots to encouragement — a contrast. "But" captures this: "English is difficult but students should not give up." This makes C the correct answer, expressing reason first, then contrast.
Answer A fails immediately because "but" in the first blank signals contrast, not reason — it would imply career opportunities somehow oppose the importance of English, which makes no sense. B uses "so" for the first blank, which implies career opportunities are a consequence of learning English being important, rather than the reason it is important — that reverses the logic. D is the trickiest distractor: it correctly identifies "because" for the first blank but then argues "but" is wrong because it only contrasts rather than showing causation. However, the passage's intent is simply to contrast difficulty with encouragement, not to show that difficulty causes the need to persist — so "but" is actually the right fit.
Remember: always match the connector to the direction of logic — reason (because), result (so), or contrast (but) — before selecting your answer.
Question 3
A teacher asks students to complete this task: 'Express your opinion about mobile phones in schools and give one reason.' Here are four student answers:
Which student has made an error in using a connector that changes the intended logical relationship between their opinion and their reason?
- Sofiia: 'I think mobile phones should be banned in schools because they distract students from their lessons.'
- Pavlo: 'I think mobile phones are useful in schools because teachers can use them to share educational materials quickly.'
- Lesia: 'I think mobile phones should be allowed in schools so students can use them for research and learning purposes.'
- Artem: 'I think mobile phones are harmful in schools so they distract students and lower their concentration levels.' (correct answer)
Explanation: When working with connectors in English, you need to understand the logical relationship each one signals. "Because" introduces a cause or reason, while "so" introduces a result or consequence. Mixing these up completely reverses the logical flow of a sentence, even if the individual ideas are correct.
Look at answer D carefully: Artem says mobile phones are harmful so they distract students. The word "so" signals that the distraction is a consequence of being harmful — as if "being harmful" causes distraction to happen afterward. But that's logically backwards. The distraction is the reason phones are harmful, not the result of it. Artem should have written "...because they distract students," which would correctly present distraction as the explanation for why phones are harmful. By using "so," Artem accidentally implies he's about to describe what harm leads to, not what causes the harm in the first place.
Choices A and B are both correct: Sofiia and Pavlo each use "because" to properly introduce a reason that justifies their stated opinion. The logic flows naturally in both cases. Choice C uses "so" correctly — Lesia says phones should be allowed so students can use them for research. Here, "so" means "in order to," expressing a purpose, which is a grammatically and logically valid construction for this context.
A useful strategy: whenever you see "because," ask yourself "does what follows explain why?" and whenever you see "so," ask "does what follows describe a result or purpose?" If the answer is no, a connector error has likely been made.
Question 4
Read the conversation between two students:
Olena: 'I think we should study in the library tonight.'
Dmytro: 'I disagree. The café is better it has free Wi-Fi and comfortable seats.'
Olena: 'That's true, the library is quieter, so I can concentrate better.'
Which pair of connectors correctly completes Dmytro's and Olena's statements in the blanks, preserving the logical relationship of each opinion to its reason?
- because / but — Dmytro gives a cause for preferring the café, and Olena introduces a contrasting reason that supports her own view (correct answer)
- so / because — Dmytro states a result of the café being better, and Olena gives a cause for the library being quieter
- but / so — Dmytro contrasts the café with the library, and Olena states a result of her preference for quiet
- because / so — Dmytro gives a cause for preferring the café, and Olena states a result of the library being quieter rather than a contrast
Explanation: When answering questions about connectors (also called conjunctions or linking words), always ask yourself two things: what logical relationship exists between the two clauses, and which connector expresses that relationship accurately? The three connectors here — because, but, and so — each signal something different: because introduces a cause or reason, but introduces a contrast, and so introduces a result or consequence.
Look at Dmytro's statement: "The café is better it has free Wi-Fi and comfortable seats." He is explaining why the café is better — the Wi-Fi and seats are his reason. That calls for because. Now look at Olena's response: "That's true, the library is quieter." She acknowledges Dmytro's point but then pivots to a contrasting idea that supports her original preference. That pivot requires but. So the correct pair is because / but, which is answer A.
Answer B is wrong because so in Dmytro's blank would mean the café being better is a result of something — but nothing before it establishes a cause. The logic is backwards. Answer C fails because but in Dmytro's slot would create a contrast where none exists — he isn't comparing the café to anything in that clause, he's justifying his preference. Answer D is tempting but incorrect: Olena's second clause ("the library is quieter, so I can concentrate") might seem like a result chain, but grammatically and contextually, she is contrasting her reason against Dmytro's, not stating a downstream consequence.
As a study tip, always read the full sentence before choosing a connector — trace the direction of logic (reason→claim vs. claim→result vs. contrast) to avoid traps like answer D.
Question 5
Which sentence INCORRECTLY uses a connector to support an opinion with a reason, making it logically flawed?
- I prefer dogs to cats because dogs are more loyal and easy to train at home.
- Our school canteen is good, but the portions are sometimes too small for hungry students.
- Reading books is important because it makes you smarter, so we should read every day.
- I enjoy cooking so it is a delicious hobby and makes my family very happy. (correct answer)
Explanation: When a sentence uses a connector like "so," "because," or "but," the ideas it links must follow logically from one another. "Because" introduces a reason, "so" introduces a result or conclusion, and "but" introduces a contrast. If the connector doesn't match the logical relationship between the two ideas, the sentence becomes flawed — and that's exactly what this question is testing.
Option D is the incorrectly constructed sentence. It reads: "I enjoy cooking so it is a delicious hobby and makes my family very happy." The connector "so" signals that what follows should be a result or consequence of enjoying cooking. However, "it is a delicious hobby" is not a result of enjoying cooking — it's simply a description or opinion about cooking itself. The sentence confuses a consequence with a characteristic, making the logic fall apart. A corrected version might say: "I enjoy cooking because it is a delicious hobby..." — using "because" to properly introduce a reason.
Options A, B, and C all use their connectors correctly. In A, "because" logically introduces the reason (loyalty and trainability) for the preference — that's perfectly valid. In B, "but" correctly signals a contrast between the canteen being good and the portions being small. In C, "because" introduces the reason for reading's importance, and "so" then draws a logical conclusion from that reason — both connectors work as expected.
Your strategy: always replace the connector mentally with its meaning. Ask yourself, "Does this sentence actually show a reason, result, or contrast?" If the relationship doesn't match the connector, the sentence is flawed.
Question 6
Mykola says: 'I think online classes are better than traditional classes. Students can study from home, they save time on commuting. , some students miss the social interaction of a real classroom.'
Which combination of connectors correctly fills both blanks so that Mykola's speech presents a supported opinion followed by a balanced contrasting point?
- so / But — the first connector shows commuting time as a result of studying from home; the second introduces the contrasting drawback (correct answer)
- because / So — the first connector gives commuting as the reason for studying at home; the second states a consequence of missing interaction
- but / Because — the first connector contrasts studying from home with saving time; the second gives a reason for missing social interaction
- so / Because — the first connector shows saving time as a result; the second introduces a reason for the contrasting point rather than a contrast itself
Explanation: When completing a sentence with connectors, always ask yourself two questions: What is the logical relationship between the clauses? and What does the sentence need to do at that specific point? Here, Mykola is building a supported opinion and then acknowledging a counterpoint — a classic argue-then-balance structure.
For the first blank, the sentence reads: "Students can study from home, they save time on commuting." The saving of time is a result of studying from home, not a reason for it. This calls for a result connector — so. For the second blank, Mykola shifts to a contrasting idea: " , some students miss social interaction." This pivot needs a contrast connector — But. Together, so / But correctly mirrors the structure: support the opinion, then balance it with a drawback. That makes A the correct answer.
B fails because because reverses the logic — it would mean commuting saves time causes someone to study at home, which is backwards. The second connector So then implies missing interaction is a consequence of something, which distorts the meaning entirely.
C is wrong because but between "study from home" and "save time on commuting" creates a false contrast — saving time is not opposing studying from home, it's a benefit of it.
D gets the first blank right (so is correct), but Because in the second blank introduces a reason rather than a contrast, which breaks the balanced-counterpoint structure Mykola needs.
Your tip: when a sentence presents an opinion followed by a drawback, look for a result connector + contrast connector pairing. Mixing them up is the most common trap on connector questions.
Question 7
Read the four student responses to the question: 'Should schools have more physical education classes?'
Which student response MOST effectively uses a connector to support an opinion with a clear and logical reason?
- Yulia: 'I think schools should have more PE classes, so sport is good for health and students need to exercise every day.'
- Ivan: 'I think schools should have more PE classes because students who exercise regularly tend to focus better in other lessons too.' (correct answer)
- Daryna: 'I think schools should have more PE classes, but physical activity helps students stay healthy and feel energetic all day.'
- Bohdan: 'I think schools should have more PE classes, but they are already very popular and students enjoy them a lot.'
Explanation: When answering questions about connectors in opinion writing, ask yourself two things: does the connector grammatically fit the sentence structure, and does it create a logical relationship between the opinion and the reason? These two criteria together determine whether a response is truly effective.
Ivan's response in B does both perfectly. The connector "because" introduces a cause-and-effect relationship — it signals that what follows is a direct reason for the opinion stated. "Students who exercise regularly tend to focus better in other lessons too" is a specific, logical justification that flows naturally from the claim. This is exactly how you support an opinion effectively.
Now look at why the others fall short. A uses "so," which typically introduces a result or consequence, not a reason — meaning the logic runs backwards. Yulia is essentially saying the conclusion first and then restating the premise, which creates a confused argument. C uses "but," which is a contrast connector — it signals that the next idea will contradict or limit the first. However, Daryna's second clause actually agrees with and supports her opinion, making "but" completely illogical here. D also misuses "but" in a similarly contradictory way — Bohdan says PE classes need more time, then uses a contrasting connector to say they're already popular, which actually undermines his own argument rather than supporting it.
Your strategy: memorize the function of each connector type. "Because" = reason, "so" = result, "but" = contrast. On exam questions like this, quickly identify what relationship the connector creates and check whether the sentence actually matches that relationship.
Question 8
A student is asked to give an opinion about healthy eating and support it with a reason. She says: 'I think eating vegetables is important they give your body vitamins, many teenagers prefer fast food.' Which option correctly completes her response so that she both supports her opinion AND acknowledges an opposing reality?
- so / because — she first states a result of vegetables being important, then gives a reason why teenagers prefer fast food
- because / but — she first gives a reason for her opinion, then contrasts it with the opposing reality about teenagers (correct answer)
- because / so — she first gives a reason, then presents the preference for fast food as a consequence of eating vegetables
- but / because — she first contrasts vegetables with vitamins, then gives a reason for teenagers preferring fast food
Explanation: Коли вам потрібно висловити думку та одночасно визнати протилежну реальність, зверніть увагу на логічний зв'язок між частинами речення. Запитайте себе: яка роль кожної частини — обґрунтування, контраст чи наслідок?
У цьому реченні студентка робить дві речі: пояснює, чому овочі важливі, і визнає, що підлітки все одно обирають фастфуд. Слово because вводить причину або обґрунтування — «овочі дають вітаміни» пояснює, чому вони важливі. Слово but вводить контраст — «але багато підлітків обирають фастфуд» визнає протилежну реальність. Отже, варіант B (because / but) точно відображає структуру: спочатку причина, потім контраст.
Варіант A невірний, бо so виражає наслідок, а не причину — «so they give vitamins» означало б, що важливість овочів є результатом чогось попереднього, а не пояснює її. Крім того, because тут пояснює перевагу фастфуду, а не контрастує з нею.
Варіант C помилковий, бо so у другій частині подає перевагу підлітків до фастфуду як наслідок вживання овочів, що логічно безглуздо.
Варіант D невірний, бо but на початку створює контраст між «овочами» та «вітамінами» — а вони не є протилежностями. Логічна структура повністю руйнується.
Корисна порада: коли бачите питання про сполучники, спочатку визначте функцію кожної частини речення (причина? наслідок? контраст?), а потім підбирайте сполучник, що відповідає саме цій функції.
Question 9
Which sentence demonstrates the CORRECT use of 'but' to acknowledge a limitation while still maintaining a positive opinion about a topic?
- I love travelling by train, but so does my sister, and she travels every weekend without any problems at all.
- I love travelling by train but it arrives on time and the seats are always comfortable for long journeys.
- I love travelling by train, but the ticket prices have increased a lot recently and that makes it hard for many families. (correct answer)
- I love travelling by train, but travelling by train is a great way to see the countryside and relax during the trip.
Explanation: When you see a question testing the word "but," remember its core grammatical purpose: it signals a contrast or concession. In opinion sentences, "but" introduces a limitation that counters or qualifies the positive feeling expressed before it. The structure should be: positive opinion + but + genuine drawback or limitation.
Option C does this perfectly — "I love travelling by train, but the ticket prices have increased a lot recently and that makes it hard for many families." The speaker maintains their positive view while honestly acknowledging a real disadvantage. This is the classic concession structure: you hold your opinion AND recognize its weakness simultaneously.
Now look at why the others fail. Option A uses "but" to introduce something that agrees with the first clause — the sister also loves trains. There is no contrast at all; "but" is completely misused here. Option B makes a similar logical error in the opposite direction: "it arrives on time and seats are comfortable" are additional positives, not limitations. Using "but" before more praise creates a contradiction in logic. Option D is perhaps the trickiest trap — it essentially repeats the original idea ("travelling by train is a great way...") rather than contrasting it. The sentence goes in a circle instead of introducing any genuine limitation.
A useful tip: whenever you evaluate a "but" sentence, mentally replace "but" with "however." If the second half genuinely pushes back on the first half, the usage is correct. If it adds, agrees, or repeats — the "but" is wrong. This contrast-check works reliably across similar questions.
Question 10
A student writes: 'I like summer more than winter, I can go swimming every day.' Which connector best fits the blank, and why would the other options be inappropriate in this specific context?
- 'because' — it introduces the reason that supports the opinion about preferring summer, linking cause to the stated preference (correct answer)
- 'so' — it introduces the result of liking summer, showing that the preference leads to the activity of swimming every day
- 'but' — it introduces a contrasting idea that balances the opinion with an opposing point about swimming
- 'so that' — it introduces the purpose of liking summer, suggesting the student chooses summer in order to swim
Explanation: Коли ви бачите завдання на вибір сполучника, перше, що потрібно зробити — визначити логічний зв'язок між двома частинами речення. Запитайте себе: друга частина пояснює причину, наслідок, мету чи контраст?
У цьому реченні студент висловлює думку («я люблю літо більше, ніж зиму»), а далі йде пояснення чому — можливість щодня плавати. Друга частина відповідає на питання «чому ти так вважаєш?», тобто є причиною вподобання. Саме тому правильна відповідь — A) because: цей сполучник вводить причину, яка обґрунтовує думку чи почуття.
Розберімо, чому інші варіанти не підходять. B) so вказує на наслідок — тобто перша частина спричиняє другу. Але тут логіка зворотна: саме можливість плавати є причиною вподобання, а не навпаки. C) but вводить контраст або протиставлення, якого тут немає — обидві частини речення узгоджуються, а не суперечать одна одній. D) so that вказує на мету — тобто студент навмисно обирає літо для того, щоб плавати, ніби це свідома стратегія. Однак речення описує вподобання та його причину, а не цілеспрямований вибір.
Порада: Запам'ятайте просту перевірку: якщо можна поставити питання «чому?» перед другою частиною — потрібен because. Якщо питання «що з цього випливає?» — потрібен so. Ця різниця між причиною і наслідком часто є ключовою пасткою у подібних завданнях.
