Answer:
d. Symbols generally have either an exclusively positive or negative meaning.
Explanation:
The term symbol, originating in the Greek symbolon, designates a type of sign in which the signifier (concrete reality) represents something abstract (religions, nations, amounts of time or matter, etc.) by virtue of convention, similarity or semantic contiguity (as in the case of the cross that represents Christianity, because it is a part of the whole that is the image of the dead Christ). Charles Sanders Pierce has developed a general classification of signs. As a sign, "symbol" is always something that represents something else (to someone).
The "symbol" is an essential element in the communication process, being widespread in everyday life and in the most varied aspects of human knowledge. Although there are symbols that are internationally recognized, others are only understood within a particular group or context (religious, cultural, etc.), it can also be an object that replaces, represents, or suggests something.
one example is the many colonies they had for gold and other natural resources.
Answer: Positron Emission Tomography (PET)
Explanation: A Positron Emission Tomography (PET) scan can be simply referred to as an imaging test that helps to tell or show doctors how how organs or tissues are functioning. This test involves the uses of special dyes which is made up of radioactive tracers, they are either injected or inhaled by patient depending on the organ which the test is to be carried out on.
So the next best technique Veda could use as she doesn't have access to an fMRI machine is the Positron Emission Tomography (PET).
Using this technique, the PET scanner can trace the special dyes contain radioactive tracer as they are more concentrated on areas or part of the organs with high chemical activities, this could help her get information about brain activity during the card task.
Explanation:
If richer regions can attract more investment than poorer regions because of their larger ex ante tax bases, then fiscal federalism adversely affects the growth prospects of poorer regions by reducing the resources available for either central or regional governments to fund valuable projects in poorer regions.Often geographical constraints, market imperfections, government policies, a lack of law & order, identity, per capita income and various socio-economic reasons can contribute to regional disparity such that some regions are more backward than other areas falling within the same nation
