Question

look at these details from a paragraph about the same topic: the outsides of pine cones have patterns of repeated triangles. many flowers have petals that look like hearts or ovals. honeycombs in beehives are made up of small hexagons. choose the main, or central, idea that ties all the details together. shapes can be seen throughout nature. some buildings are created with unusual shapes. pine cones have lots of small triangles on the outside. tree trunks are filled with rings that are circles.

Explanation:

The details mention shapes in pine - cones, flowers, and beehives, all of which are natural elements. The central idea should cover all these examples. The first option "Shapes can be seen throughout nature" ties them together as it encompasses the shapes found in the natural items described. The other options focus on specific natural items or on buildings (which is not part of the given natural - item details).

Answer:

Shapes can be seen throughout nature.
