Miranda is conducting a poll to determine how many students would attend a students-only school dance if one was held. Which sample is most likely to yield a representative sample for the poll?

A representative poll should give students throughout the school a fair chance of being selected. Pulling twenty names from each grade from a container holding the entire student body's names randomly selects students across grades. The other samples are limited or self-selected: town pedestrians may not be students, Miranda's classes may not reflect the whole school, and newspaper writers choose themselves to respond.
