It has been suggested that older men in all cultures tend to marry women younger than themselves because men are genetically predisposed to seek female features associated with youthful fertility. This suggestion best illustrates
a. social learning theory.
b. behavior genetics.
c. freudian psychology.
d. an evolutionary perspective

This suggestion best illustrates D. an evolutionary perspective.

Explanation:

The evolutionary perspective seeks explanations for behaviors taking into consideration our species need to adapt and reproduce. From this perspective, our behaviors result from problems our ancestors encountered over 10,000 years ago. Since the purpose of the species is to perpetuate itself, many of our behaviors could be explained by the instinct of reproduction. We look for good mates in order to procreate. That perspective would, therefore, explain men who marry younger women as a result of our reproductive needs - young means fertile, at least instinctively.

all freedom fighters demanded for constitution. so british finally granted india it's freedom. then a constituent assembly was formed. it's chair man was rajendra prasad and its deputy chairman was dr. br ambedkar.

this assembly take the time of about one year than our constitution was finally formed.

explanation:

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)
