Which body part helps roundworm prevent their body from expanding? | [
"scales",
"plate",
"skin",
"tough cuticle covering"
] | D | Roundworms have a tough covering of cuticle on the surface of their body. It prevents their body from expanding. This allows the buildup of fluid pressure in their partial body cavity. The fluid pressure adds stiffness to the body. This provides a counterforce for the contraction of muscles, allowing roundworms to move... | SCiQ_train |
The sun is a star of average size and brightness. From Earth, the sun appears as a round, yellow object in the daytime sky. At night, we see other stars. They appear as tiny points of light. Why does the sun appear larger than stars that we see at night? | [
"Daylight brightens the sun, making it appear larger.",
"Starlight bends as it passes planets, making the stars appear smaller.",

"25",
"35",

"40"
] | B | volume of a cylinder = pi*r^2 *h
r=10
h=10
volume = 1000pi
volume of the cone: 2000pi
volume of the cone = pi*r^2 * h/3
2000=r^2 * h/3
1st case: r=10 -> h/3=20 => h=60
2nd case: h=10 -> r^2 = sqrt(600)
sqrt(600) = 10*sqrt(6)
sqrt(6)>sqrt(4)

What occurs when light interacts with our atmosphere? | [
"prism effect",
"rayleigh scattering",
"rainbow formation",
"eclipse"
] | B | Rayleigh scattering occurs when light interacts with our atmosphere. The shorter the wavelength of light, the more strongly it is disturbed by collisions with atmospheric molecules. So blue light from the Sun is preferentially scattered by these collisions into our line of sight. This is why the sky appears blue. | SCiQ_train |

A florist has 2 azaleas, 3 buttercups, and 5 petunias. The florist puts two flowers together at random in a bouquet. However, the customer calls and says that she does not want two of the same flower. What is the probability that the florist does not have to change the bouquet? | [
"11/15",
"14/45",
"31/45",
"23/45"
] | C | The probability that two of the same flowers were chosen:
P(AA) = 2/10 * 1/9 = 2/90
P(BB) = 3/10 * 2/9 = 6/90
P(PP) = 5/10 * 4/9 = 20/90
The sum of these probabilities is 14/45
P(two flowers are different) = 1 - 14/45 = 31/45

It would take one machine 5 hours to complete a large production order and another machine 4 hours to complete the same order. How many hours would it take both machines, working simultaneously at their respective constant rates, to complete the order? | [
"D 5/21",
"A 9/20",
"C 7/19",
"B 20/9"
