Final answer:
Pete should set the quality parameter of the video to 'high' in Adobe Flash Player to prioritize display quality over playback speed.
Step-by-step explanation:
Pete is designing a web page and wants to use Adobe Flash Player to play videos with a focus on display quality over playback speed. To achieve this, Pete should set the quality parameter of the video to 'high'. When the quality parameter is set to high, it ensures that the video will be displayed with the best quality possible, even if this means that the video might buffer or play back with less speed on slower internet connections or less capable devices. This setting prioritizes the visual experience for users who want to see the clothing lines with the highest image clarity and detail.
