An educational bias in problem solving could:. a. prevent an adult from seeing a solution evident to a child
b. produce language or mathematical solutions instead of form or spatial solutions
c. produce the appearance of racial, ethnic, or age differences in problem solving ability
d. all of the above

All of the  Above  ( D )

Explanation:

An educational bias in problem solving could provide all of the above listed options because an educational bias is said to be when a certain group of people in an educational setting is been treated negatively due to their : Gender, race, cultural beliefs, language or age.

Even though some of the educational bias might be unintentional they are bound to produce differences in educational solutions like having a mathematical solution instead of a spatial solution and also producing a racial or age difference problem in the solving ability of student faced with educational bias.  

its b i looked it up hope u get it right wish u luck

the earth’s crust is broken into separate pieces called tectonic plates (fig. 7.14). recall that the crust is the solid, rocky, outer shell of the planet. it is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. both types of crust rest atop solid, upper mantle material. the upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

each tectonic plate is free-floating and can move independently. earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. the term fault is used to describe the boundary between tectonic plates. most of the earthquakes and volcanoes around the pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. other observable results of short-term plate movement include the gradual widening of the great rift lakes in eastern africa and the rising of the himalayan mountain range. the motion of plates can be described in four general patterns:

collision: when two continental plates are shoved together

subduction: when one plate plunges beneath another (fig. 7.15)

spreading: when two plates are pushed apart (fig. 7.15)

transform faulting: when two plates slide past each other (fig. 7.15)
