We Have Lift-Off

E4
A guy called Brad Edward says space elevators must be built to reduce the risks of shuttles. He's planning to build a carbon nanotube ribbon that's three feet wide, anchored somewhere in Ecuador, stretching a mind-numbing 72,000km upwards into space. The centrifugal force of Earth's rotation will keep the ribbon taut. (The space elevator will slide up and down the ribbon, but that's immaterial to the problem). The problem is - if I sneak onto the platform in Ecuador and snip off the ribbon at its base, what will happen?
No good? Try this instead: Ms Arnold's home was recently the site of a pre-wedding party for her daughter. In attendance were Ms Botti, Ms Connor and Ms Densgrove, with their three unmarried daughters. Figure out each woman's full name, who the mothers are and who are the daughters from the four clues given: (1) Amy, Candice, Delia and Dot are all old friends of the bride-to-be and her mother; (2) Three of the four women in their twenties were Ann, Beth's daughter and the woman in that generation whose first and last initials are the same; (3) Three of the four women in their forties were Candice, Delia's mother and the woman in that generation whose first and last initials are the same; (4) Beverly and Carol are the same age.
DEAR MS
(The problem was to figure out how many centimetres of a blue and yellow pencil will be smeared with paint after the tenth move of a centimetre each when the blue pencil, which is smeared with paint, is slid against the side of the yellow pencil six times alternately. - MS)
Pencil-Pushers Dept:
When the blue pencil is held firmly against the yellow pencil, the paint from the blue pencil is smeared on the yellow pencil, so that both pencils have 1cm of paint. And when the blue pencil is slid down 1cm, pressed against the yellow pencil, an extra 1cm of paint is smeared on the yellow pencil. In the next upward movement of the blue pencil, the yellow pencil gets 1cm more. At the end of two moves, both pencils have 2cm of paint. So, in the end, both pencils are smeared with 6cm of paint.

(The other riddle was: "You throw away the outside and cook the inside. Then you eat the outside and throw away the inside. What did you just eat?" - MS)
Corny-Riddle Dept:
The answer is corn. When we get corn from the plant, we remove the husk and cook it. After cooking it, we eat the kernels and throw away the cob. 
- Niraj Nandish, nirajnandish@icloud.com
The answer is an ear of corn. You throw away the husk and cook the kernel. Then you eat the kernel and throw away the cob. 
- Jaelyne Tauro, jaelynetauro@gmail.com
Corn on the cob, because you throw away the husk (outside); cook it (inside) and eat the kernels (outside), and throw away the cob (inside).

Works with most non-veg foods too. Throw away skin/feathers, cook and eat meat, throw away bones.

(Meanwhile, a reader has some more regarding the LOX problem. - MS)
More-Or-Lox Dept:
I would like to point out that in your question "Can a human being drown in a pool of liquid oxygen which is at room temperature?", you totally did not mention the presence of any perfluorocarbon liquid. It was just OXYGEN.

(Yes, you're correct, but my idea was only to show that breathing a liquid with a high oxygen content is possible. - MS)
ENDGAME 
How do you account for the fact that if any set of integers is repeated six times to form another integer it must (almost) always be divisible by 7? (Examples: 121212121212, 111111, 555555, 451451451451451451, 909090909090, etc.) Can anyone think of exceptions?
