Ateacher wants to know how many students like to dance in his school. which of the following samples would be most representative of the entire school? he interviews 20 random students coming out of a ball. he interviews the cheerleading squad. he interviews 20 random students in the hall. he interviews the other teachers.

20 random students in the hall.
If they are coming out of a ball the sample can be biased because they (more than likely) like to dance. The cheerleader are only a small population (cheerleading is dance oriented as well.) Teachers won't know for sure.

“The Charge of the Light Brigade”

Summary

The poem tells the story of a brigade consisting of 600 soldiers who rode on horseback into the “valley of death” for half a league (about one and a half miles). They were obeying a command to charge the enemy forces that had been seizing their guns.

Not a single soldier was discouraged or distressed by the command to charge forward, even though all the soldiers realized that their commander had made a terrible mistake: “Someone had blundered.” The role of the soldier is to obey and “not to make reply...not to reason why,” so they followed orders and rode into the “valley of death.”

Complete Text

Half a league, half a league,

Half a league onward,

All in the valley of Death

  Rode the six hundred.

‘Forward, the Light Brigade!

Charge for the guns!’ he said:

Into the valley of Death

  Rode the six hundred.

‘Forward, the Light Brigade!’

Was there a man dismay’d?

Not tho’ the soldier knew

  Someone had blunder’d:

Their’s not to make reply,

Their’s not to reason why,

Their’s but to do and die:

Into the valley of Death

  Rode the six hundred.

Cannon to right of them,

Cannon to left of them,

Cannon in front of them

  Volley’d and thunder’d;

Storm’d at with shot and shell,

Boldly they rode and well,

Into the jaws of Death,

Into the mouth of Hell

  Rode the six hundred.

Flash’d all their sabres bare,

Flash’d as they turn’d in air

Sabring the gunners there,

Charging an army, while

  All the world wonder’d:

Plunged in the battery-smoke

Right thro’ the line they broke;

Cossack and Russian

Reel’d from the sabre-stroke

Shatter’d and sunder’d.

Then they rode back, but not

  Not the six hundred.

Cannon to right of them,

Cannon to left of them,

Cannon behind them

  Volley’d and thunder’d;

Storm’d at with shot and shell,

While horse and hero fell,

They that had fought so well

Came thro’ the jaws of Death,

Back from the mouth of Hell,

All that was left of them,

  Left of six hundred.

When can their glory fade ?

O the wild charge they made!

  All the world wonder’d.

Honour the charge they made!

Honour the Light Brigade,

  Noble six hundred!v
