Question

they are soft and bend easily
question 2
why are nonmetals helpful in ride seating and harnesses?
they conduct heat and electricity
they are flexible, soft, and insulating
they are heavy and strong
they are shiny and smooth
question 3
what makes metalloids different from metals and nonmetals?

Explanation:

Non - metals are not good conductors of heat and electricity (so the first option is wrong). For ride seating and harnesses, flexibility, softness (for comfort), and insulating properties (to prevent heat or electrical transfer which could be uncomfortable or dangerous) are important. Non - metals are generally not heavy and strong (metals are often heavy and strong in some cases, but that's not a non - metal property here) and being shiny and smooth is not a key property for seating and harnesses.

Answer:

They are flexible, soft, and insulating
