The correct answer would be that substance A is rice, and substance B is sugar.
For substance A to be filtered out, it means that A is a water-insoluble substance and for substance B to be recoverable by evaporating off the water, it means that B is water-soluble.
Thus, A can neither be sugar nor alcohol because neither can be recovered by filtration. Also, B can neither be coffee nor alcohol because they can not be recovered as residue through evaporation of water.
Therefore, the only correct answer is that substance A is rice, and substance B is sugar because rice can be filtered out from water while the water-soluble sugar can be recovered by evaporating the water.

Answer:
318,6 ms-1
Explanation:
Como sabemos que la relación entre la velocidad del sonido en el aire y la temperatura viene dada por;
V = 331√T / 273
Dónde;
V = velocidad del sonido
T = temperatura en kelvin = (-20) + 273 = 253 K
V = 331√253 / 273
V = 318,6 ms-1
