Read the following article from a website.
The county of Tavish has fourteen low dams on the Merrin and its creeks, most built in the 1800s to power grist mills. Several are now cracking, and the provincial government has offered to pay for taking down as many as five of them so that trout can swim upstream. Council must choose by the end of June which dams, if any, to put forward. The offer has divided the small towns that grew up beside the old mills.
Maren Pellerin, a river scientist with the watershed authority, wants as many dams removed as the money allows. “The water in the ponds above the dams is four degrees warmer than the river below them,” she said. “Trout need cold water, so for them every pond is a barrier.” Pellerin also wants money set aside for the silt piled up behind each dam before a single stone is moved. “If that silt washes downstream all at once, it will bury the gravel beds where fish lay their eggs,” she warned.
Gideon Ostrander, who chairs the county heritage society, disagrees. “These walls are the reason our towns exist at all,” he said. “Every spring, school groups come to watch the mill wheel turn in Harlow, and it turns only because the dam holds back the water.” He would rather see a channel lined with rock built around each dam, so fish can pass while the stone stays. “A fish can swim around a wall,” Ostrander added. “A town cannot build its history a second time.”
Henrietta Paquin, the county engineer, says the cost of insuring the cracked dams has doubled in five years. “Some of these structures are failing inspection, and the county cannot keep paying to protect a risk,” she said. Paquin supports removing any dam that fails, but adds that “a trail detour and water testing have to be in the budget from day one.” Femi Oyelaran, who runs a small hydro plant on one dam, wants council to slow down. “On the hottest days of summer, my turbine keeps the lights on for twelve farms nearby,” Oyelaran said. “Rank every dam by the power it makes and the harm it does to fish. Then take out the worst ones first, not simply the easiest.”

Correct Answer: whether to take down old dams on a local river
Why this is correct: The province has offered to pay for removing some of the old dams. Every person in the article reacts to that offer.
Passage Reference: the provincial government has offered to pay for taking down as many as five of them so that trout can swim upstream
Tips: Go through Pellerin, Ostrander, Paquin and Oyelaran, asking each time if the option fits. Narrow options match one moment in the story, while the topic matches the story as a whole.
Why the other options are wrong:
- a fight over fishing licences on the river: Trout come up in the article, but nobody talks about fishing licences.
- a plan to turn the old mills into museums: Ostrander wants to keep the dams, but nobody plans museums.
- a new rule for building near the riverbank: No building rule is discussed in the article.
Correct Answer: the case for keeping the old walls
Passage Reference: He would rather see a channel lined with rock built around each dam, so fish can pass while the stone stays.
Why this is correct: Paragraph three belongs to Ostrander. He says the walls are why the towns exist, and he wants rock channels so fish can pass while the stone stays.
Tips: Go over “Paragraph three” once more and ask what it adds to the story. Choose the option that names that, not a detail from another part.
Why the other options are wrong:
- the reasons council must decide by June: The June deadline comes in paragraph one, not paragraph three.
- the rising cost of insuring weak dams: Insurance costs are Paquin’s point, and they come in paragraph four.
- a count of the trout that use the river: The article never counts the trout in the river.
Correct Answer: a newspaper for readers in the county
Passage Reference: The offer has divided the small towns that grew up beside the old mills.
Why this is correct: The story is about a choice the county council must make. It quotes local people and says the offer has divided the small towns beside the old mills.
Tips: Look back over the article as a whole. Picture each publication named in the options, and ask if it would run this exact story.
Why the other options are wrong:
- a guide for people who fish for trout: Trout are mentioned, but the article gives no advice on fishing.
- a national journal of engineering research: The article reports one county’s choice. It presents no research findings.
- a magazine about building power plants: One small hydro plant is mentioned, but the article never explains how to build one.
Correct Answer: fish losing the places where they breed
Passage Reference: If that silt washes downstream all at once, it will bury the gravel beds where fish lay their eggs
Why this is correct: Pellerin says that if the silt washes down all at once, it will bury the gravel beds where fish lay their eggs.
Tips: Find the sentences where Pellerin speaks and read them closely. Keep the option she predicts, and drop any that another speaker raises or nobody raises.
Why the other options are wrong:
- the ponds above the dams drying out: Nobody says the ponds would dry out.
- farms nearby losing their electric power: Power for the farms is Oyelaran’s point about the turbine, not Pellerin’s warning about silt.
- the town’s drinking water turning cloudy: Pellerin does not mention drinking water.
Correct Answer: a study showing some dams do far more damage to fish than others
Passage Reference: Rank every dam by the power it makes and the harm it does to fish.
Why this is correct: Oyelaran wants every dam ranked by the power it makes and the harm it does to fish. A study showing that some dams do much more damage would back that ranking.
Tips: Go through Oyelaran’s sentences one by one. Would each option give weight to Oyelaran’s plan, or does it belong with somebody else?
Why the other options are wrong:
- a finding that trout come back quickly once the dams come down: This fits Pellerin, who wants as many dams taken down as the money allows.
- a history showing the towns grew up around the mills: This fits Ostrander’s case for keeping the walls.
- a report that insurance on the cracked dams has doubled: This fits Paquin’s case for removing dams that fail.
Correct Answer: fourteen
Passage Reference: The county of Tavish has fourteen low dams on the Merrin and its creeks
Why this is correct: The article says Tavish County has fourteen low dams on the Merrin and its creeks.
Tips: This blank needs a count for the whole county. Several numbers appear, so check what each one counts.
Why the other options are wrong:
- five: Five is the most dams the province will pay to remove. It is not the total.
- twelve: Twelve is the number of farms that Oyelaran’s turbine helps.
- forty: This number is not in the article.
Correct Answer: four degrees
Passage Reference: The water in the ponds above the dams is four degrees warmer than the river below them
Why this is correct: Pellerin says the water in the ponds above the dams is four degrees warmer than the river below.
Tips: The commenter is repeating the river scientist’s figure. Find her comparison between the ponds and the river.
Why the other options are wrong:
- three degrees: Pellerin gives a slightly bigger difference than this.
- six degrees: Pellerin gives a smaller difference than this.
- eight degrees: Pellerin gives a much smaller difference than this.
Correct Answer: school groups
Passage Reference: Every spring, school groups come to watch the mill wheel turn in Harlow
Why this is correct: Ostrander says school groups come every spring to watch the mill wheel turn in Harlow.
Tips: The commenter means the heritage chair. Find who he says visits each year, and what they come to see.
Why the other options are wrong:
- bus tours: Ostrander does not mention bus tours.
- local families: Ostrander does not say local families come to watch.
- painting classes: Painting classes are not mentioned in the article.
Correct Answer: a trail detour
Passage Reference: a trail detour and water testing have to be in the budget from day one.
Why this is correct: Paquin says a trail detour and water testing have to be in the budget from day one.
Tips: Find what the engineer says the budget must include. Choose the item that goes with water testing.
Why the other options are wrong:
- a fish ladder: Paquin does not mention a fish ladder. Ostrander suggests a rock channel instead.
- a new bridge: No bridge is mentioned in the article.
- a parking lot: No parking lot is mentioned in the article.
Correct Answer: 1800s
Passage Reference: most built in the 1800s to power grist mills
Why this is correct: The article says most of the dams were built in the 1800s to power grist mills.
Tips: This blank needs a time. Find when the article says the dams were first put up.
Why the other options are wrong:
- 1700s: The dams are younger than this.
- early 1900s: The dams are older than this.
- 1920s: The dams are about a hundred years older than this.
