Answer:
A. to build tension in the story
Explanation:
Option A is the correct answer.
This is true because from the passage, we discover that Father Wolf is introduced. As he makes that sound and stated that "It is time to hunt again", there is a feeling of anxiety and fear that tends to well up in the reader. At this point, the reader will want to discover what happens next.
Then the reader's feeling of anxiety heightens when "a little shadow with bushy tail" is introduced into the the scene. At this time, the reader feels that something will happen between Father Wolf and that creature. This scenario actually describes how tension is developed in a story.
The answer would be 15.
The first equation would be ∠1 = 15°
Then the second equation is ∠2 = (3 * 15 + 30)° which simplifies to 75°
And since complementary angles need to equal 90° to be true we have to add both angles. So, ∠1 (= 15°) + ∠2 (= 75°) = 90°. Now that we know they equal 90°, 15 would be the answer to your problem.
C is not the right answer as it does not even include name of the artist, Di Vinci. The correct answer is A. Leonardo Di Vinci is best known for his fantastic paintings and sculptures but he was also an inventor and invented the ariel screw, the parachute, and several war machines.
