which procedure will most increase the energy output of a nuclear reactor? exposing the core to the outside world
removing fissile material from the core
decreasing the amount of steam produced
raising the control rods out of the reactor

decreasing the amount of steam produced    

A nuclear reactor is a system in which simulatenous fission of the heavy nuclear atomic particles takes place with the help of radiation source. The energy output can be increased by the prevention of the dissipation of heat in the form of steam in the external environment.

d

Explanation:

raising the control rods is the answer on edge. took the test.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
