Question

reread the underlined phrases in the passage. what idea about the long - term use of avs do these phrases convey? 1) avs are very simple machines to build and operate. 2) avs can understand gestures and facial expressions. 3) avs are unable to replace human drivers right now. 4) avs can make logical decisions in heavy traffic.

Explanation:

To solve this, we analyze each option:

• Option 1: AVs (Autonomous Vehicles) are complex, not "very simple machines", so this is incorrect.
• Option 2: AVs do not rely on understanding gestures/facial expressions (they use sensors/algorithms), so this is incorrect.
• Option 3: The "long - term use of AVs" implies a future state. If AVs can’t replace human drivers now, it suggests the long - term idea is that they are not ready to do so yet, which fits.
• Option 4: Making logical decisions in heavy traffic is not the main idea conveyed by the "long - term use" phrase; AVs’ current limitations in replacing humans are more relevant.

Answer:

C. AVs are unable to replace human drivers right now. (Assuming the third option is labeled C; adjust the label based on the original question’s numbering if needed.)
