Liquid, because the melting point of Sample A is 126°C.

multiple mass values of each metal were tested, but in Experiment 2, the same mass value of each metal was tested.

. Suppose Study 2 had been repeated, except in a lab kept at −1°C. The total volume of runoff measured over the 600 min in the repeated study would most likely have been

near or at zero, because −1°C is below the freezing point of water.

The researchers conducting the studies chose to use a box made of a type of plastic rather than of wood to ensure that all of the water from the melting ice would flow from the box and into the trough. The researchers most likely made that choice because that type of plastic, unlike wood, is:

nonporous and impermeable, and therefore inca- pable of absorbing water.

. It can reasonably be inferred from the passage that the small satellite galaxy referred to in lines 35-36 is

the Sagittarius Dwarf.

. According to the author, Berry's solos as a recording session musician were often very short because he:

worked within the recording constraints of the era.
