The passage below is adapted from an essay on the history of agriculture and botany.

Paragraph 1 (lines 1–11)
For centuries after Spanish explorers introduced vanilla to Europe, the plant remained a frustrating botanical mystery. While vanilla vines grew vigorously in the royal greenhouses of Paris and London, they stubbornly refused to produce the valuable seed pods. European botanists were unaware that in its native Mexico, the vanilla orchid (Vanilla planifolia) shared an exclusive mutualistic relationship with the tiny Melipona bee, the only insect capable of navigating the flower's complex anatomy to fertilize it. Without this specific pollinator, the plants in Europe and its Indian Ocean colonies remained sterile, rendering commercial cultivation outside of Mexico seemingly impossible.

Paragraph 2 (lines 12–23)
The impasse was broken in 1841 on the island of Réunion by Edmond Albius, a twelve-year-old enslaved youth with a keen eye for botany. Albius discovered that the membrane separating the orchid's male and female organs—the rostellum—could be gently lifted with a small bamboo splinter and the pollen pressed onto the stigma using one's thumb. This elegant, manual method bypasses the need for the Melipona bee entirely. Albius’s simple, rapid technique allowed workers to pollinate hundreds of flowers in a single morning, suddenly making large-scale production of the labor-intensive crop feasible.

Paragraph 3 (lines 24–35)
Albius's innovation transformed the global spice trade, turning Réunion and Madagascar into world leaders in vanilla production and dramatically lowering the cost of the luxury spice. Despite the immense wealth generated for plantation owners and colonial economies, Albius himself received little benefit. He was freed when slavery was abolished on the island in 1848, but he spent the remainder of his life working as a kitchen servant and died in poverty. His contribution, though foundational to a multi-million-dollar global industry, brought him neither financial security nor widespread recognition during his lifetime.

Match each paragraph of the passage to its primary paragraph-level main idea.

  • Paragraph 1 (lines 1–11)An explanation of the ecological barriers that historically restricted vanilla production to its region of origin.
  • Paragraph 2 (lines 12–23)A description of the practical botanical technique that resolved the cultivation impasse.
  • Paragraph 3 (lines 24–35)An account of the global economic consequences of a cultivation breakthrough and the fate of its creator.

Cevap

Paragraph 1 matches the ecological barriers of vanilla production; Paragraph 2 matches the practical botanical technique of hand-pollination; Paragraph 3 matches the economic consequences and the fate of its creator.
Each paragraph corresponds to a unique step in the narrative: the first sets up the ecological problem of pollination; the second explains the manual botanical solution; the third details the global financial impact and the personal fate of the inventor.

Adım Adım Çözüm

1
Analyze Paragraph 1 to determine its main focus.
Paragraph 1 focuses on the botanical mystery of why vanilla could not produce seed pods in Europe, attributing it to the absence of the Melipona bee, which is native to Mexico. This equates to an ecological barrier.
To match the paragraph to its main idea, we must synthesize the details into a single central concept.
2
Analyze Paragraph 2 to determine its main focus.
Paragraph 2 introduces Edmond Albius and outlines the manual steps he developed to fertilize the vanilla orchid using a bamboo splinter. This is a description of a practical technique.
Determining the shift in focus from Paragraph 1's problem to Paragraph 2's specific mechanical solution allows for a correct match.
3
Analyze Paragraph 3 to determine its main focus.
Paragraph 3 discusses the transformation of the global spice trade, the wealth generated, and the fact that Albius himself lived and died in poverty.
Aligning the dual focus of macroeconomic growth and the inventor's personal hardship matches this paragraph with the third description.
