The following paragraphs are from an essay about the history of cartography.
Paragraph 1
Early modern cartographers relied on highly artistic, hand-drawn maps that blended geography with folklore, often filling unexplored ocean territories with drawings of mythical sea monsters. These maps served not only as navigational aids but also as status symbols for wealthy merchants and monarchs who commissioned them. However, as trade routes expanded across the Atlantic and Pacific, sailors demanded maps that prioritized mathematical precision over aesthetic embellishment.
Paragraph 2
[1] This projection preserved straight lines of constant bearing, allowing sailors to chart courses by drawing a single straight line across the map. Despite distorting the relative size of landmasses near the poles, the map revolutionized maritime navigation and became the standard for sea travel.
Which choice provides the most effective transition from the preceding paragraph to the paragraph that follows?
- ACartographers started using mathematical grids to help sailors, Gerardus Mercator designed a new type of projection in 1569.
- BGerardus Mercator was highly interested about cartography and spent years working on geographic problems.
- In 1569, Gerardus Mercator resolved this issue by developing a grid-based projection.Answer
- DTo satisfy this demand, Gerardus Mercator creates a new grid system in 1569 that will help sailors chart their courses.
