Question

What additional content would best clarify the information in the passage?

a detailed description of attempts to create homemade skateboards before 1960

an brief explanation of how polyurethane wheels improved skateboards

a description of the most common traditional skateboard tricks

an explanation of the manufacturing process used to produce surfboards

Answer 1

Commercial production of skateboards began in earnest in the 1960s with the Makaha and Hobie boards. These boards were clearly influenced by surfboards and surfing style. They were an instant hit. More than 50 million boards were sold in just three years.

Over time, construction advancements made skateboards both safer and more maneuverable. These improvements included polyurethane wheels, laminated decks, kicktails (the upward-curving piece at the back of the board), and larger and lighter boards. These advancements in boards led to the invention of new tricks.

Answer 2

is B

Answer 3

Hm,
I'm not really sure on this one..
So, let's see if the process of elimination gets us anywhere...

It's definitely not A, because no where in the passage does it talk about home-made skateboards.

I don't believe it would be D either, because that really doesn't help us at all.

I would go with B or C .
