Someone had to do it....so here are the answers. There will NOT be a test at the end.

1. Male ladybugs are called ladybugs too....even though they're not technically bugs. They're beetles.
2. Orange the fruit was definitely named before its corresponding color was.
3. The answer is the telephone is arranged in that order so the alphabet to each number will correspond in the correct number. When the telephone was first used peoples numbers were not just numbers they were call letters and numbers. The keypad has a different reason. Calculators were made in the beginning with tubes, Before 1964, calculators were either mechanical or electronic devices with heavy tubes. The key pads on the first calculators actually resembled old cash registers, with the left row of keys numbering 9 on top down to 0 on the bottom.
4. Darkness travels at the speed of light. More accurately, darkness does not exist by itself as a unique physical entity, but is simply the absence of light. Any time you block out most of the light – for instance, by cupping your hands together – you get darkness.
