Answer:
C. full featured
Explanation:
You need to make use of the full-featured version of the word processing programs to use the illustrations that are part of the program. And simple versions might not have that.

Answer:
INSERT INTO Movie(Title,Rating,ReleaseDate)
VALUES("Raiders of the Lost ArkPG",'PG',DATE '1981-06-15'),
("The Godfaher",'R',DATE '1972-03-24'),
("The Pursuit of Happyness",'PG-13',DATE '2006-12-15');

a. stateTaxRate - A good variable name because it represents what it holds, the state sales tax rate, without being too wordy. Also correctly capitalized in camelcase.
b. txRt - A bad variable name because while short and simple, it is too hard to understand what the variable represents.
c. t - A very bad variable name if you plan on using the variable often. Far too short and you will forget what it represents and is needed for.
d. stateSalesTaxRateValue - A bad variable name because it is just too wordy. Cutting it down to A's variable name is much more reasonable
e. state tax rate - A bad variable name and probably invalid because it has spaces in the name.
f. taxRate - A good variable name if there are no other tax calculations other than state tax rate. Otherwise you would confuse state vs local tax rate or something, making it a bad variable name.
g. 1TaxRate - A bad variable name because the number 1 has no reason being in the variable name. It doesn't add anything to the name.
h. moneyCharged - A bad variable name because it is not specific enough in explaining why the money is being charged and what for.
