Raymond, a researcher, is conducting a study on child development. after observing several infants, he finds that parental conflicts have no effect on babies as they are too young to understand. which of the following, if true, would weaken raymond's argument? a. babies understand the facial expressions of people around them and react accordingly. b.many gifted children don't recognize or develop their skills until adolescence. c.a baby's early achievements—such as reaching, sitting, crawling, or talking—are rarely good indicators of intelligence. d.babies are oblivious to parental yelling because they are at a development stage when they are only aware of their physiological needs.

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.

you probably know the answer. stop asking stupid questions and making me waste my time. j.k. ; )   b.t.w. what are three ratios equivalent to 5 : 11? thx

where is the passage
