In the past 30 years, there has been nearly a fourfold increase in the incidence of skin cancer in the united states.
The most prevalent form of cancer is skin cancer. Squamous cell carcinoma, basal cell carcinoma, and melanoma are the three main kinds of skin cancer. While melanoma is far less prevalent than the other forms, it is significantly more likely to spread to other parts of the body by invading adjacent tissue. Melanoma is the skin cancer that most commonly results in mortality.

All skin tones, including those with darker complexions, are susceptible to developing skin cancer. People with dark skin tones are more prone to develop melanoma in places that aren't often exposed to the sun, such as the soles of their feet and the palms of their hands.

The Aswan Dam, or more specifically since the 1960s, the Aswan High Dam, is an embankment dam built across the Nile in Aswan, Egypt between 1960 and 1970. Its significance largely eclipsed the previous Aswan Low Dam initially completed in 1902 downstream. Based on the success of the Low Dam, then at its maximum utilization, construction of the High Dam became a key objective of the government following the Egyptian Revolution of 1952; with its ability to better control flooding, provide increased water storage for irrigation, and generate hydroelectricity the dam was seen as pivotal to Egypt's planned industrialization. Like the earlier implementation, the High Dam has had a significant effect on the economy and culture of Egypt.
Before the High Dam was built, even with the old dam in place, the annual flooding of the Nile during late summer had continued to pass largely unimpeded down the valley from its East African drainage basin. These floods brought high water with natural nutrients and minerals that annually enriched the fertile soil along its floodplain and delta; this predictability had made the Nile valley ideal for farming since ancient times. Since this natural flooding varied however, high-water years could destroy the whole crop, while low-water years could create widespread drought and associated famine. Both these events had continued to occur periodically. As Egypt's population grew and technology increased, both a desire and the ability developed to completely control the flooding, and thus both protect and support farmland and its economically important cotton crop. With the greatly increased reservoir storage provided by the High Aswan Dam, the floods could be controlled and the water could be stored for later release over multiple years.
I think it is B. before the constitution, the government could not collect taxes. C and D aren’t accurate statements
2 is the answer at least I remember
