The ability to generalize a study's results to different circumstances is known as external validity that suffers from 7 types of threats.
<h3>What are the threats to External Validity?</h3>
There are 7 major threats to external validity.
- The first threat is sampling bias, in which a sample is not representative of the population.
- The second threat is history, where an unrelated incident can affect the results.
- The third threat is observer bias, in which the traits or actions of the experimenter unintentionally affect the results, resulting in bias and other demand features.
- The fourth threat is the Hawthorne effect, which describes the propensity for individuals to alter their behaviour merely because they are aware that they are being observed.
- The fifth threat is the Testing Effect, in which the results are impacted by whether a test is administered before or after another.
- The sixth threat is the aptitude-treatment, which involves the interaction of individual and group factors to affect the dependent variable.
- The environment, time of day, location, researcher traits, and other variables that restrict the generalizability of the results are included in the seventh threat.

Answer:
For close to 50 years, educators and politicians from classrooms to the Oval Office have stressed the importance of graduating students who are skilled critical thinkers.
Content that once had to be drilled into students’ heads is now just a phone swipe away, but the ability to make sense of that information requires thinking critically about it. Similarly, our democracy is today imperiled not by lack of access to data and opinions about the most important issues of the day, but rather by our inability to sort the true from the fake (or hopelessly biased).
We have certainly made progress in critical-thinking education over the last five decades. Courses dedicated to the subject can be found in the catalogs of many colleges and universities, while the latest generation of K-12 academic standards emphasize not just content but also the skills necessary to think critically about content taught in English, math, science and social studies classes.

Answer:
750
Explanation:
<em>I'm gonna make my best effort here... (it's been a long hecking time since SAT math last year :P)</em>
Set both equation equal:
5x = -15x + 3000
20x = 3000
x = 150
Plug into any equation because both are equal anyway:
y = 5x
y = 5(150)
y = 750
(a, b) --> (x, y)
The point is (150, 750) and b = 750
The example of "happy violence" that George Gerbner describes is c. Mean-world syndrome.
<h3>What is the mean-world syndrome?</h3>
The mean-world syndrome is a belief by people that the world is more dangerous than it actually is.
As a result, they enjoy action movies which reinforce this belief and leads to happy violence where people are glad that the danger in the world is being taken care of.
Options for this question include:
A. Entertainomericials
B. Cultivation Theory
C, Mean-world syndrome
