Marge read that the universe is expanding and the galaxies are moving apart. this, the book says, is similar to how raisins and nuts placed on dough spread out when the dough rises. what is a likely misconception this could cause in marge’s mind? a- the galaxies are shaped like raisins b- the universe will expand forever c- there are galaxies beyond the known universe d- galaxies are found only in the outer part of the universe

A misconception that this example could cause it that galaxies are found only in the outer part of the universe. Galaxies have various shapes, oval, spiral, double spiral (like our own galaxy) and explaining them like raising could make someone thinks that they are only in the outer part of the universe, like raisins. Beside from this fact, the example is a clear method to explain the expansion of the universe, and how galaxies are going apart from each other.

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
