Answer:
In their House of Sound, Fran Scott and Greg Foot investigate how drums work.
Drums have been around for thousands of years and throughout history have often been involved in warfare -something they are reminded of as they play along to Mars from Holst’s The Planets suite.
Using confetti placed on a drum they use a slow motion camera to reveal how the confetti behaves like air molecules when the drum is struck.
The skin of the drum vibrates and makes the confetti dance.
As the air molecules vibrate against each other, sound waves are formed and the sound of the drums can be heard.
Fran explains that the pitch of a drum depends on how tight its skin is. If the skin is tight the drum makes a high note, if it is slack it makes a low note.
Greg points out the amount of air inside a drum also influences its pitch. The more air in a drum, the lower the note. The less air in a drum, the higher the note.
Volume depends on the size of the vibrations that are made.
Hit a drum hard and this makes big vibrations and a loud sound.
Hit a drum softly and the vibrations are smaller and the sound not as loud.
Together they make a drum kit out of things that can be found around the house, and Fran shows us how to make fun drums out of a plastic bowl and half a balloon.

Explanation:
A. because it is just right
In general, the coming of the Industrial Revolution led to a situation in which women became more subjugated to men and were allowed to have less contact with the public sphere. The idea about gender roles that arose from the Industrial Revolution is sometimes called the idea of “separate spheres.”
Before the Industrial Revolution, most work occurred at home and everyone in the family worked together as a unit. There was very little distinction, if any, between work and home or between economic activity and non-economic activity. For this reason, women were seen as part of the economic unit and had a role that was not too dissimilar to that played by men.
As the Industrial Revolution progressed, this changed. Work came to be something that was performed away from home. The ideal was that women would not work outside the home. They would stay home and perform work that was not paid. This meant that there came to be the sense that women belonged at home and outside the economic sphere while men belonged outside the home in the economic world.
