An interesting observation made by the firefighters was that some parts of the forest seemed to escape the flames. the crown fire would drop down into a ground fire in these areas, and then jump back up into the canopy as the fire burned into adjacent areas. they observed that many of these areas had previously been thinned, which means that some of the trees were cut down and hauled away to be used as timber. in other areas, thinned forests burned with as much severity as the unthinned forest. your objective is to design an observational study to answer the question: what was the determining factor for areas that escaped the worst impacts of the fire, compared to areas that were severely burned? select the best hypothesis and prediction that follow from the question you're trying to answer. for getting started, see t

levels of production can be increased by technology while holding labor and capital constant, because increased technology makes the production process more efficient. subsequently, the lras curve is almost a vertical line, that can shift to the right, with an increase in technology.

the relationship between the lras curve and the ppc is that both can make the economy could grow. the ppc achieves that when it shifts outward because of more resources or technological advances while the lras curve shifts if more resources are developed or if there are technological advances.

the lras curve is a vertical line at an output level that represents the number of goods and services a nation can produce over a sustained period using all of its productive resources as efficiently as possible with all of the current technology available to it.

the production possibilities frontier (ppf) is a graphical device that is used for economic analysis of production decisions because the ppf measures the maximum possible combinations of two goods that an economy is capable of producing with its currently available resources and technology.

what are the answer choices?
