Respuesta correcta: A)Coffee farming in the Tarrazu valley has changed over the last decade.
A)Coffee farming in the Tarrazu valley has changed over the last decade.Correct: it names the topic and adds the writer's angle, so it can control every other sentence.
B)The road up to the farm is steep and the turns are very narrow.This is a supporting detail about the road, but it cannot carry the whole main idea.
C)My uncle grows coffee on three hectares near San Marcos.It is a personal example about one relative, so it narrows the focus too much.
D)Last March I drank four cups of coffee in a single morning.A funny anecdote that stands alone and does not build any general idea.

Karla writes about how she prepared for the English exam at her school in Heredia.
Which sentence should Karla cut because it breaks paragraph unity?
Elige una opción para comprobar tu respuesta.
Respuesta correcta: C)Last summer my cousin won a prize in mathematics in Limon.
💡 Explicación
Unity means every sentence in a paragraph develops one single idea. A true detail about an unrelated event is still off topic and weakens the focus, so it is cut or moved.
Ver respuesta
Respuesta correcta: C)Last summer my cousin won a prize in mathematics in Limon.
A)I made a vocabulary list and reviewed it every night for a month.This is a concrete action that supports the topic and gives evidence for the habit.
B)My teacher suggested practice tests from the ministry website.It names a useful source of practice, so it explains how she actually prepared.
C)Last summer my cousin won a prize in mathematics in Limon.Correct to cut: it changes person, place and subject, so it breaks unity with the topic.
D)On exam day I felt nervous, but I answered every single item.It reports her feelings on exam day, which belongs to the preparation topic.
💡 Explicación
Unity means every sentence in a paragraph develops one single idea. A true detail about an unrelated event is still off topic and weakens the focus, so it is cut or moved.

Respuesta correcta: B)The Alajuela Saturday market, a lively tradition, offers produce and crafts.
💡 Explicación
A good topic sentence names the subject and covers the whole paragraph. It must also be a little broader than any single detail that follows, or those details fall outside its range.
Ver respuesta
Respuesta correcta: B)The Alajuela Saturday market, a lively tradition, offers produce and crafts.
A)The Alajuela Saturday market sells vegetables that taste wonderful.It limits the paragraph to produce and its quality, so crafts would fall outside the frame.
B)The Alajuela Saturday market, a lively tradition, offers produce and crafts.Correct: it names the place, adds detail, and is broad enough to hold the whole paragraph.
C)Last Saturday, after breakfast, we left the house at seven in the morning.It narrates the speaker's morning, but it never says what the paragraph is about.
D)Marta and I carried four bags because the stalls close at noon.It is only a detail, and without a main idea first the reader has no frame.

Respuesta correcta: D)Topic sentence, then the details in time order, then the conclusion.
💡 Explicación
The standard path is topic sentence, then supporting sentences following a clear sequence, then a concluding sentence. Time order or numbered steps belong in the middle of the paragraph.
Ver respuesta
Respuesta correcta: D)Topic sentence, then the details in time order, then the conclusion.
A)Conclusion first, then the topic sentence, then the supporting sentences.Starting with the conclusion inverts the path, because the idea must be announced first.
B)Supporting sentences, then the conclusion, then the topic sentence.Details before the main idea leave the reader guessing, and nothing has been opened yet.
C)Topic sentence, then the conclusion, then the supporting sentences.The conclusion arrives before the support, so it has nothing to summarise.
D)Topic sentence, then the details in time order, then the conclusion.Correct: the idea is announced, developed step by step, and then closed with a summary.

Which sentence links those two study habits with the right logical relation?

Respuesta correcta: A)By contrast, the library in town is quiet but it closes early.
💡 Explicación
Connectives must match the real logical link. Contrast words signal difference, cause words signal a result, and example words signal support, so a wrong link misleads the reader.
Ver respuesta
Respuesta correcta: A)By contrast, the library in town is quiet but it closes early.
A)By contrast, the library in town is quiet but it closes early.Correct: 'By contrast' marks a difference, which is exactly the link between the two situations.
B)As a result, Alonso now studies in the forest when the weather is fine.'As a result' signals a consequence, yet the two habits are alternatives and not effects.
C)For example, he carries a notebook and two pens to the reserve.'For example' introduces evidence, so a general claim has to come before it.
D)In the same way, both places suit students who read a lot.'In the same way' joins similar points, but these two places are opposed and not parallel.

Respuesta correcta: B)As a result, the park reopened the trail so hikers could walk again.
A)However, the park reopened the trail so hikers could walk again.'However' signals contrast, but no opposing idea appears here, only a cause and its effect.
B)As a result, the park reopened the trail so hikers could walk again.Correct: 'As a result' presents the dry week as the cause and the reopening as the effect.
C)In addition, the park reopened the trail so hikers could walk again.'In addition' adds extra weight, yet the second sentence is a consequence and not a bonus point.
D)Otherwise, the park reopened the trail so hikers could walk again.'Otherwise' shows what happens if a condition fails, which is hypothetical here.

A)On the first Saturday of the month, forty neighbours came with spades.A concrete example that supports the argument, but it is not a closing move.
B)The city has three parks and one very small playground for children.A neutral fact about facilities that ends the paragraph without any conclusion.
C)Trees give shade, absorb carbon dioxide and reduce noise on busy roads.This is a body sentence with reasons, so it belongs before the closing appeal.

Respuesta correcta: A)I cycle to school every morning, and the ride takes about twenty minutes.
💡 Explicación
A tight paragraph states each point once. Repeating a time phrase, hiding the action inside nouns, or stacking synonyms all add length without adding information for the reader.
Ver respuesta
Respuesta correcta: A)I cycle to school every morning, and the ride takes about twenty minutes.
A)I cycle to school every morning, and the ride takes about twenty minutes.Correct: one idea, one clean pair of clauses, and no fact is stated twice.
B)I cycle to school every single morning, and in the morning I cycle to school.'Every morning' and 'in the morning' repeat the same time, so one of them should go.
C)Cycling is something I do, and my activity in the morning is cycling too.This is wordy nominalisation, because the action is hidden inside nouns instead of verbs.
D)I cycle, I also pedal, and furthermore I ride my bicycle to school.Three verbs describe one single action, so the paragraph swells without gaining meaning.

B)English is spoken in many countries around the world today.It is a true general fact, but it names no local outcome, so it stays outside her claim.
C)Her cousin got a tourism job in Heredia after passing an English exam.Correct: it shows a real job in Heredia that followed from English, so it proves her point.
D)English has a very large number of words and irregular verbs.This describes the language itself, not the effect English had on anyone's employment.

B)It introduces new information that the paragraph never developed.Correct: a concluding sentence must wrap up the developed idea and never open a fresh topic.
C)It is too short to be accepted as a real sentence.A short sentence can summarise perfectly well, so length is not a test of a conclusion.

Respuesta correcta: C)Small coffee growers deserve higher prices than the market now offers.

C)Small coffee growers deserve higher prices than the market now offers.Correct: it states a debatable claim that evidence in the paragraph could defend.
D)Green hills roll north from Turrialba toward the Caribbean lowlands.A descriptive sentence about the landscape, which paints a picture and takes no stand.

A)Grind the beans, heat the water, filter the grounds, then pour the coffee.Correct: every step grows out of the previous one, so the reader can follow the method.
B)Drink the coffee, grind the beans, heat the water, filter the grounds.Drinking comes first here, which reverses the process before anything has been made.
C)Heat the water, drink the coffee, pour the coffee, grind the beans.Drinking and pouring appear before heating and grinding, so the order breaks in the middle.

Respuesta correcta: D)Because buses are slow and overcrowded, the city should invest in rail.
A)Buses in San Jose are sometimes late, and the roads are busy at seven.It offers two observations only, and a thesis must take a position that evidence can support.
B)Public transport is a topic that everybody in the capital can discuss.It announces a topic but takes no stand, so there is nothing there for the paragraph to argue.
C)There are many buses, and there are also trams, and there are routes.It merely counts the services and repeats the same opening, so no argument appears.
D)Because buses are slow and overcrowded, the city should invest in rail.Correct: it states what the city should do and gives the reason the evidence will confirm.

Respuesta correcta: D)Add a topic sentence at the start and group the details under it.
A)Add two more sentences so the paragraph becomes longer and richer.More length never fixes a missing opening, because the reader still cannot see the focus.
B)Copy the whole paragraph onto a new page and begin again there.Changing the page changes nothing, since what matters is the order of the ideas inside.
C)Repeat the first sentence at the end to close the paragraph.Copying a sentence creates redundancy, and a real conclusion has to develop the point.

A)Nevertheless, the new aqueduct was opened in Alajuela last year.'Nevertheless' signals contrast, yet no previous sentence states an opposing idea.
B)Opened in Alajuela last year, the structure is still in use today.Correct: an alternative name keeps the reference clear without repeating the same noun.
C)It is very long, and it is also expensive, and it is also modern.Stacking 'it is' clauses with 'also' adds no information and blurs the reference.
D)Alajuela, a city in the valley, is a city that has an aqueduct.This shifts the focus to the city, so the paragraph describes a place and not the aqueduct.
