Passage Reference: . Gregorio Dano is a seahorses fisherman, and he's not happy. A decade ago, he and the other subsistence fishers from the central Philippine village of Handumon supported their families by collecting dozens of seahorses a day from the coral reefs of nearby Danajon Bank. But as the six-month-long seahorse-fishing season begins next month, Dano will be lucky to catch a half dozen of the elusive fish in a full night's diving, enough to buy only a day's worth of rice.

Tips: If a paragraph is built around one person's story, the best heading often names that person.

Why the other options are wrong:

• Regulating fishing activities: Fishing rules are not discussed here. The paragraph focuses on one man's situation, not laws or controls. This is a wrong focus trap.
• Finding ways to protect seahorses: Protection solutions appear later in the passage, not here. This paragraph only describes the problem. This is a wrong section trap.

Key Vocabulary:

• subsistence = basic survival
• elusive = hard to find

Question Focus: Main idea - why seahorses are unusual and highly demanded

Passage Reference: B. Seahorses and their relatives, the only animal species whose males, rather than females, become pregnant, are popular with home collectors and public aquariums alike. Since the charismatic fish die easily in captivity, they must be replaced frequently from the wild. Dried seahorses are prized by practitioners of traditional Chinese medicine, in remedies for everything from asthma to impotence. As disposable income in China has risen over the last decade, so too has demand for seahorse-based cures. That has caused overfishing at Danajon Bank and throughout the fishes' range, leading to the loss of at least 20 million wild seahorses a year. Populations have been plummeting everywhere seahorses are fished -'in sea grass beds and mangrove stands from Florida to Ecuador, and on coral reefs from India to Vietnam.

Why this is correct: The paragraph explains what makes seahorses unusual and desirable, including male pregnancy and their use in aquariums and medicine. These special traits explain why they are heavily exploited.

Tips: Choose a heading that covers ALL main points, not just one example.

Why the other options are wrong:

• Medicinal use of seahorses: Medicine is only one part of the paragraph. The paragraph also discusses aquariums and biological uniqueness. This is a partial truth trap.
• Finding ways to protect seahorses: No solutions are discussed here, only causes of decline. This is a wrong section trap.

Key Vocabulary:

• charismatic = attractive
• plummeting = falling fast

Question Focus: Main idea - scientific efforts to stop population decline

Passage Reference: C. Last week 35 researchers and representatives of major public aquariums from around the world met at Chicago's John G. Shedd Aquarium to discuss what can be done to reverse the trend. 'We've seen population declines of 50 per cent over the last five years, and that's unacceptable,' says Amanda Vincent, a conservation biologist at Montreal's McGill University and co-founder of Project Seahorse. One way to reduce aquariums' dependence on wild stocks is to improve captive breeding techniques. Jorge Gomczjurado, a biologist at San Francisco's Steinhart Aquarium, has spent the last year trying to raise Hippocampus ingens, the Giant Pacific seahorse. Prized as the largest of the seahorses at up to 12 inches long, H. ingens is also one of the trickiest to breed. Like all seahorses, they're fussy eaters, and in captivity they're susceptible to disease. By experimenting with food supplements, Gomezjurado has managed to raise three successive generations.

Why this is correct: This paragraph is about solutions, especially captive breeding, to protect seahorses. The focus is on research and action to reverse population decline.

Tips: Headings about solutions usually include ideas like research, improvement, or reducing damage.

Why the other options are wrong:

• Stephen Casey's effort: Stephen Casey appears in the next paragraph, not here. This is a wrong section trap.
• Peculiar creatures: The paragraph is not describing what seahorses are like, but how to save them. This is a context shift trap.

Key Vocabulary:

• reverse = stop and change direction
• susceptible = easily affected

Question Focus: Main idea - one researcher's field study on seahorse movement

Passage Reference: s. D. Another researcher, a Ph.D. candidate at the London Institute of Zoology named Stephen Casey, has been studying the six-inch-long Tiger-Tail seahorse (H. comes), the most heavily exploited species on the Danajon Bank. Casey spent six weeks in Handumon, going out with seahorse fishers nightly to collect specimens. He paid the fishers the going rate for their catch, a few pesos each, which allowed him to sample without further depleting the population. His research will help determine whether seahorses can move from one spot on a reef to another. Adults rarely stray more than a few feet from their small home range, but juveniles might be transported to distant areas by waves or currents. If so, the progeny of an isolated pocket of reproducing adults would spread out, recolonizing distant reefs that have been depopulated by fishing.

Why this is correct: The paragraph focuses entirely on Stephen Casey's research, explaining what he studied and why it matters for conservation.

Tips: When a paragraph follows one person's actions from start to end, the heading usually names that person.

Why the other options are wrong:

• Tiger-Tail seahorses: The species is mentioned, but only as part of Casey's research. The main idea is the researcher, not the animal. This is an example-as-main-idea trap.
• Regulating fishing activities: No rules or regulations are discussed here. This is a wrong focus trap.

Key Vocabulary:

• exploited = overused
• recolonizing = returning to live again

Question Focus: Main idea - helping villagers earn money without fishing seahorses

Passage Reference: ing. E. The Shedd Aquarium is tackling the depopulation problem from a different angle. Together with Project Seahorse, Shedd's merchandizing department developed a project with the Handumon villagers to lessen their dependency on seahorses. The Shedd gift shop now stocks 34 diffeient products made by Handumon fishers and their families. Straw beach mats and handbags with seahorse motifs are big sellers. Dano and his wife have gone into business making wooden diving goggles, sold at the Shedd gift shop for $7, and have earned enough to get out of debt and buy food and medicine for their six children.

Why this is correct: The paragraph shows how villagers earn money from new products, not seahorses. This directly describes alternative income sources.

Tips: If a paragraph talks about jobs, money, or products, look for headings about income or livelihoods.

Why the other options are wrong:

• Sustainable Fishing techniques: Fishing methods are not discussed here. This is about crafts and selling goods. This is a wrong focus trap.
• Gregorio Dano: Dano is mentioned, but the paragraph is mainly about the project, not his life story. This is a partial truth trap.

Key Vocabulary:

• dependency = reliance
• merchandising = selling products

Question Focus: Main idea - long-term fishing solutions and protection zones

Passage Reference: ldren. F. Project Seahorse is also encouraging traditional Chinese medicine practitioners to identify alternatives to seahorses, and the researchers are helping villagers to develop sustainable fishing techniques. The villagers have established an 80-acre "no fishing' zone around Handumon. Populations of both seahorses and other species have rebounded so well that the idea is spreading to other villages, says Philippine biologist Marivic Pajaro, though the fish suffered a setback a year ago when the night watchman sneaked away to attend a fiesta and the area was poached of seahorses.

Why this is correct: This paragraph is about sustainable fishing, including no-fishing zones and alternatives to harmful practices.

Tips: Words like sustainable, zone, and rebound usually signal long-term solutions.

Why the other options are wrong:

• Regulating fishing activities: There is no mention of government rules or enforcement systems. The focus is community sustainability. This is a context shift trap.
• Medicinal use of seahorses: Medicine is only briefly mentioned and not the main focus. This is a partial truth trap.

Key Vocabulary:

• sustainable = long-term and safe
• rebounded = increased again

Question Focus: Main idea - cooperation between all groups involved

Passage Reference: ahorses. G. As the workshop concluded last week, Vincent said she was more hopeful than ever before that seahorse decline can be reversed before disaster strikes. She now hopes to get all of the "stakeholders', including fishers, traders, medical practitioners and biologists, to meet together and work out how best to manage seahorses so that all parties - including the fish - get what they need. "Fish are seen as food, not wildlife," says London Zoo curator and Project Seahorse co-founder Heather Hall, summing up the difficulty of preserving underwater species. 'We're just lucky that seahorses are about as cute as you get in the fish world." Those good looks may be what eventually saves them in the wild. The researchers hope that less popular but equally threatened species that share their watery homes may be saved

Why this is correct: The paragraph stresses cooperation between fishers, traders, scientists, and others. Working together is clearly the main idea.

Tips: Conclusion paragraphs often focus on cooperation, hope, or future plans.

Why the other options are wrong:

• Finding ways to protect seahorses: Protection is mentioned, but the emphasis is on cooperation, not methods. This is a too general trap.
• Peculiar creatures: This paragraph is about people and policy, not seahorse biology. This is a wrong focus trap.

Key Vocabulary:

• stakeholders = involved groups
• preserving = protecting

General Tips:

• Read all headings first and underline key words before matching them to paragraphs.
• Focus on the main idea of each paragraph, not one interesting detail.
• Headings follow paragraph order, so use the previous answer to help locate the next.
• If two headings seem possible, choose the one that covers more of the paragraph.
