Which of the following best reflects why lighting systems are used when filming on location outdoors? (Select all that apply.)

Digital cameras need strong concentrated light to produce any images, so natural light is not sufficient.

Strong light means lower-cost production, so artificial light saves money on processing.

To produce a film image you have to manage how light interacts with the film or digital media, and “natural” light may not look natural.

Because filming on location is expensive, it is often important to be able to film even when the weather does not cooperate.

1. ask the user how many questions are in the quiz. 2. ask the user to enter the key (that is, the correct answers). there should be one answer for each question in the quiz, and each answer should be an integer. e.g., 34 7 13 100 81 3 9 10 321 12 might be the key for a 10-question quiz. you will need to store the key in an array. 3. ask the user to enter the answers for the quiz to be graded. there needs to be one answer for each question. note that these answers do not need to be stored; each answer can simply be compared to the key as it is entered. 4. when the user has entered all of the answers to be graded, print the number correct and the percent correct. 5. add a loop so that the user can grade any number of quizzes with a single key. after the results have been printed for each quiz, ask "grade another quiz? (y/n)." note: you only have one array (the key). you are not creating a new key for each set of quiz answers.
