Question

as animation technology developed, the cost of producing an animation ____, which meant that people could spend more money on making animations ____.

○ decreased; longer
○ increased; shorter
○ decreased; with sound
○ increased; without dialogue

Explanation:

1. Analyze the first blank: With the development of animation technology, production efficiency usually improves, so the cost of producing an animation should decrease (not increase, so options with "increased" are wrong).
2. Analyze the second blank: If production cost decreases, people can allocate resources to make animations with more features. Making animations "longer" is a possible result, but the option "decreased; with sound" is more about a technological - related improvement in animation quality. In the early days of animation, adding sound was a technological advancement. As production cost decreased (due to technological development), people could afford to add sound to animations. "Longer" is a bit vague compared to the specific improvement of adding sound. So the correct combination is "decreased; with sound".

Answer:

C. decreased; with sound (assuming the options are labeled A, B, C, D in order, where C is "decreased; with sound")
