完整解法

1. Estimate the volume of a standard cup of milo

A standard cup or mug holds about $200$ to $300\text{ ml}$ of liquid.

$20\text{ ml}$ is too small (about a tablespoon).
$20\text{ l}$ is too large (about a large bucket or water dispenser bottle).
$200\text{ l}$ is extremely large (a bathtub).
Therefore, $200\text{ ml}$ is the only reasonable estimate.

答案

$200\text{ ml}$ (option 3)
