Hoi!
A cost-benefit analysis is an estimate of the pros and cons of carrying out an action. Often, a cost-benefit analysis is made of an action that can have a significant impact on other things.
The correct answers are:
The type of technology used within the school
The equipment needed in the cafeteria to provide healthy or unhealthy lunches
The equipment needed for art facilities within the school.
These projects deserve a cost-benefit analysis because they can have a rather significant impact on the success of the school.
For some of us, it began late at night: huddled under bedroom covers with our ears glued to a radio pulling in black voices charged with intense emotion and propelled by a wildly kinetic rhythm through the after-midnight static. Growing up in the white-bread America of the Fifties, we had never heard anything like it, but we reacted, or remember reacting, instantaneously and were converted. We were believers before we knew what it was that had so spectacularly ripped the dull, familiar fabric of our lives. We asked our friends, maybe an older brother or sister. We found out that they called it rock & roll. It was so much more vital and alive than any music we had ever heard before that it needed a new category: Rock & roll was much more than new music for us. It was an obsession, and a way of life.
In the Six-Day War (1967) the countries were: Israel, Egypt, Syria, Jordan, and Iraq.
In the War of Attrition (1967-1970) countries were: Israel, Egypt, Soviet Union, PLO (Palestine Liberation Organization), and Jordan.
In the Yom Kippur War (1973) countries were: Israel, Egypt, Syria, Iraq, Jordan, Algeria, Morocco, Saudi Arabia, and Cuba.
So it would be Israel and Egypt. Sorry for that. I forgot it said 'what TWO'.
