We planted trees before the rains started because the soil was wet.
We planted trees before the rains started, so the soil was wet.
We planted trees after the rains started because the soil was wet.
We planted trees after the rains started, so the soil was dry.
Explanation:
This sentence correctly uses 'after' to show the planting happened following the rains, and 'because' gives the reason (wet soil). The timing and cause are logically consistent.
3. Select the option that shows correct punctuation after an introductory sequencing word.
Firstly, we must reduce plastic use in our town.
Firstly; we must reduce plastic use in our town.
Firstly we must reduce plastic use in our town.
Firstly: we must reduce plastic use in our town.

Farms used fertilizer, runoff carried chemicals into drains, waste from roadside stalls blocked flow, the river became contaminated.
Explanation:
This option presents steps in a logical cause-to-effect sequence: fertilizer use → runoff carrying chemicals → blocked drains worsen flow → overall contamination of the river.
5. Choose the sentence that correctly links actions in time with 'when'.
When the factory opened, smoke covers the sky.
When the factory opened smoke covered the sky.
When the factory opened, smoke covered the sky.
When the factory opened, the sky covered the smoke.
Explanation:
This sentence correctly uses 'when' to set a time, and includes the comma to separate the introductory clause. The subject and verb agree and the meaning is clear.

Explanation:
This option orders safe, logical steps for household waste management using correct sequencing words and sensible actions (composting, recycling, proper disposal).
7. Which sentence correctly uses 'after that' to sequence events?
The students collected rubbish after that, they counted the bags.
The students collected rubbish after that they counted the bags.
After that the students collected rubbish they counted the bags.
The students collected rubbish; after that they counted the bags.
Explanation:
Using a semicolon or a period before 'after that' correctly connects two related independent clauses. This option uses a semicolon to join the clauses properly.

Explanation:
'As soon as' correctly introduces the time clause and is followed by a comma before the main clause. The sentence clearly shows one event following another.
9. Which choice correctly orders sentences to form a coherent short paragraph about plastic pollution?
The community started a recycling programme. People never separated waste. Plastic bags blew into the river. Therefore fish died from pollution.
People never separated waste. Plastic bags blew into the river. Therefore fish died from pollution. The community started a recycling programme.
People never separated waste. Plastic bags blew into the river. The community started a recycling programme. Therefore fish died from pollution.
Plastic bags blew into the river. People never separated waste. The community started a recycling programme. Therefore fish died from pollution.
Explanation:
This order shows cause then effect then response: poor waste separation → bags enter river → fish die → community responds with recycling. The sequence is logical and clear.

Clean before it rains the drains to prevent flooding.
Clean the drains before, it rains to prevent flooding.
Clean the drains before it rains to prevent flooding.
Before it rains clean the drains to prevent flooding.

This sentence correctly places the main clause then the time clause 'before it rains' and clearly states purpose. The word order is natural and grammatical.
11. Which option uses transitional words correctly to list causes of air pollution?
Firstly car exhausts, secondly burning waste, thirdly factory emissions are the causes of air pollution.
Firstly - car exhausts secondly - burning waste thirdly - factory emissions are the causes of air pollution.
Firstly car exhausts secondly burning waste thirdly factory emissions are the causes of air pollution.
Firstly, car exhausts; secondly, burning waste; thirdly, factory emissions are the causes of air pollution.
Explanation:
This option uses commas after introductory words and semicolons to separate list items within a sentence, producing a clear, grammatically correct list of causes.
12. Choose the best order to write these sentences so that the sequence is clear: (1) We reported the spill to county authorities. (2) A tanker leaked oil into the river. (3) Volunteers helped contain the spill.
A tanker leaked oil into the river. Volunteers helped contain the spill. We reported the spill to county authorities.

Volunteers helped contain the spill. A tanker leaked oil into the river. We reported the spill to county authorities.
We reported the spill to county authorities. A tanker leaked oil into the river. Volunteers helped contain the spill.
Explanation:
This order shows event → response (reporting) → action (containment). Reporting quickly after the leak but before the containment is logical and shows correct sequencing.
13. Which sentence correctly connects two events with 'so' to show result?
The factory released waste, so the fish died.
The factory released waste so, the fish died.
The factory released waste, so that the fish died.
The factory released waste so the fish died.
Explanation:
Using a comma before 'so' connecting two independent clauses is correct when showing a result. The sentence clearly expresses cause and effect.
14. Select the option that orders sentences best for instructions on conducting a litter survey at school.
Meet at the hall to discuss results, divide into teams, record findings on the form, collect data on rubbish locations.

15. Which sentence correctly uses 'then' to sequence actions?
We stopped the leak then, we called the environmental officer.
We stopped the leak, then we called the environmental officer.
We stopped the leak then we called the environmental officer.
Then we stopped the leak, we called the environmental officer.
Explanation:
Placing a comma before 'then' when it joins two actions improves clarity. This shows the correct sequence: first stopping the leak, then calling for help.
16. Choose the most natural sequence to explain why a clean-up continued after the rains.
Because the rains came, the volunteers returned to continue cleaning before the river rose.
The volunteers returned and continued the clean-up because the rains started again.
The rains stopped, so the volunteers returned and continued the clean-up.
The rains delayed work; therefore, we stopped the clean-up and did not return.
Explanation:
This sentence correctly uses 'so' to link the cessation of rain (cause) to the volunteers' action (effect). The chronology is clear and logical.
17. Which option shows correct use of 'while' to indicate two actions happening at the same time?
The community cleaned the market while, the county swept the drainage channels.
While the community cleaned the market the county swept the drainage channels.
The community cleaned the market; while the county swept the drainage channels.
While the community cleaned the market, the county swept the drainage channels.
Explanation:
'While' introduces a subordinate clause showing simultaneous actions. The comma after the introductory clause makes the sentence grammatically correct and clear.
18. Select the sentence that orders instructions correctly and maintains parallel grammar.
Collect gloves, wear boots, and bring bags.
Collect gloves, to wear boots, and bring bags.

19. Which sentence correctly uses 'finally' to end a sequence?
Finally we placed, the hazardous waste at the county collection point.
Finally we placed the hazardous waste at the county collection point.
Finally, we placed the hazardous waste at the county collection point.
Finally: we placed the hazardous waste at the county collection point.
Explanation:

20. Choose the option that correctly sequences reasons using 'because' and 'therefore'.
Because factories dumped waste, therefore the water was polluted.
Factories dumped waste because therefore the water was polluted.
Therefore factories dumped waste because the water was polluted.
Factories dumped waste; therefore the water was polluted.
Explanation:
Using a semicolon before 'therefore' properly links two independent clauses showing cause and result. This clearly indicates that dumping waste led to pollution.

The river looked cleaner, fewer cases of waterborne disease were reported, volunteers felt proud.
Volunteers felt proud, the river looked cleaner, fewer cases of waterborne disease were reported.
The river looked cleaner, volunteers felt proud, fewer cases of waterborne disease were reported.
Fewer cases of waterborne disease were reported, the river looked cleaner, volunteers felt proud.
Explanation:
This sequence moves from observable result (cleaner river) to measurable outcome (fewer diseases) to emotional response (pride), presenting a logical progression of effects.
