Recall that psychologists monitored almost thirty homes throughout the city of Seattle on Halloween night. They recorded whether each trick-or-treater arrived alone or in a group. The researchers also randomly asked some children arriving alone and some arriving in groups to provide their names and addresses. The results of this study showed that children were more likely to take more treats than they were supposed to if they arrived and if they were .

In group ,not asked to provide their names and addresses

Explanation:

According to the question, research was conducted by researcher on children and adults who dress-up in Halloween times to go house to house asking for treats.These treats can be in the form of candy or money as per different places.

As the research was over,result received depicted that if children came more in group form then it is more likely for them to receive more treats due to unity and performance.They can also gain more candies if address and names were not asked from them because they will be free to go to anybody's house for treat.

two jet streams that directly affect the formation of weather in the continental part are a polar jet and a subtropical jet. they are responsible for the transportation of weather systems, which directly affect people. the polar front is the boundary between cold air from the north pole and warmer equatorial air. both the polar jet and the subtropical jet blow from the west to the east, and follow the boundary between cold and warm air.

the strongest jet streams are polar jets, while subtropical jets are somewhat weaker.

the right answer is c. the polar jet stream is generaly stronger than the subtropical jet stream.

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)
