True is the correct answer. In the language of flowers, solid or single-color carnations symbolize affirmative responses, agreement, and 'yes.' Unlike striped carnations which mean refusal, solid carnations represent positive acceptance and agreement.

Despite being called 'black box,' flight recorders are painted bright orange or red to make them easier to locate in crash debris or underwater. The term 'black box' refers to their function, not their appearance. The high-visibility orange color, often with reflective tape, helps search crews spot them quickly. White, black, or red would be less effective for visibility purposes.
