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. tree trunks are filled with rings that are circles. pine cones have lots of small triangles on the outside. shapes can be seen throughout nature.

Explanation:

The details mention shapes (triangles, hearts, ovals, hexagons) in nature (pine - cones, flowers, beehives). The central idea should generalize this, and "Shapes can be seen throughout nature" does that. The other options are too specific to one example.

Answer:

Shapes can be seen throughout nature.
