Which letter represents the triple point?

Which of the following is true about the triple point?

Albuquerque is approximately 5,500 feet above sea level, which means atmospheric pressure is less than 1 atm. In Albuquerque, will water freeze at a lower or higher temperature than it does at sea level, where the pressure is 1 atmosphere?

Albuquerque is approximately 5,500 feet above sea level, which means atmospheric pressure is less than 1 atm. In Albuquerque, will water boil at a lower or higher temperature than it does at sea level, where the pressure is 1 atmosphere?

At 1 atmosphere and room temperature (25°C), would you expect solid carbon dioxide to melt to the liquid phase, or sublime to the gas phase?

Some industrial processes require liquid carbon dioxide. Assuming we lived at sea level (1 atm), how could carbon dioxide be liquefied? Check all possibilities.
