As of July 5th, 2020, how many coronavirus cases were reported in the U.S.?

The correct answer indicates that there were reported cases of more than 2.8 million as of July 5, 2020. This data aligns with the trends observed in COVID-19 case reporting during that period. By the early days of July 2020, the spread of coronavirus had reached significant numbers, with daily reporting indicating a rapid increase in total cases. The figure of more than 2.8 million is consistent with the public health data available at that time, reflecting the severe impact of the pandemic in the United States.

It is important to understand that at this point in the pandemic, other numbers given are either too low or too high compared to available data. Just under 2 million cases would not accurately represent the state of the pandemic, given the surge in cases that was observed. Additionally, over 3 million cases would not fit the context as closely as B, as that milestone was reached a short time after that date. Meanwhile, approximately 4 million cases significantly exceeds the actual reported count as of early July 2020, further underlining why the answer more accurately reflects the situation at that time.
