The Great Pyramid, a 4,500-year-old stone tomb built for an ancient Egyptian king, contains chambers, which were rooms in which the body of the king and ceremonial objects could be placed. In addition to these chambers, the pyramid also contains four shafts-narrow tunnels that were created in the solid stone structure as it was being built(see
illustration). These shafts rise from two burial chambers and lead toward the outside of the pyramid. The four shafts are too small and placed at too steep an angle for a person to pass through them. The purpose of the shafts in the Great Pyramid is not certain, but archaeologists have several theories.
One theory is that the shafts were used for ventilation to bring fresh air from outside into the pyramid. During its construction, many workers labored inside the pyramid’s interior chambers, and they may have had difficulty breathing, especially because the fires they used to light their work space would have produced smoke. The shafts may have been constructed to make it easier for workers to breathe.
A second theory is that the shafts were deliberately positioned in relation to stars. Scientists studying the pyramid have found that its shafts align with the positions of certain stars in the sky. At certain times in ancient Egyptian history, stars played an important role in religion; specific stars were associated with particular gods. The shafts in the king’s tomb might have been built in alignment with specific stars for religious reasons.
A third theory is that the shafts were intended as passageways to help the king’s spirit enter the afterlife. Ancient Egyptians believed that the king’s spirit would leave his body and travel to the afterlife. The ancient builders may have built the shafts as openings for the king’s spirit to pass through.

Dr. Gupta:
This week, we’ll be discussing the future of education. Let’s focus now on the following viewpoint: it is no longer useful to spend many years pursuing a traditional, specialized university degree in a single field, such as communications or economics. Instead, it makes more sense for most people to complete several shorter certification programs and earn certificates in, for example, project management, computer programming, graphic design, and so on. Do you agree or disagree with this viewpoint? Why?
Andrew:
I agree that completing short certification programs makes a lot of sense these days because people are more likely to change careers now than they were in the past. Certification programs allow people to quickly learn a variety of professional skills that are in demand at the moment. And acquiring such skills leads to more job opportunities.
Claire:
I see the advantages of earning certificates, but I don’t think that they can completely replace university degrees. Certification programs provide only superficial knowledge, while university degrees offer a well – developed and organized approach to studying. By pursuing university degrees, students gain foundational knowledge and a broader understanding of their field of study and develop many skills as well.
