Interpret the following data table showing the number of cell divisions per hour for cancerous and non-cancerous cells. What trend can be observed? (I:1) [table]
Time (Hours) | Non-cancerous Cell Count | Cancerous Cells Count 0 | 100 | 100 1 | 105 | 120 2 | 110 | 144 3 | 115 | 173
[/table]

Begin by restating what the data table shows: time in hours (0 to 3) and the corresponding counts of non-cancerous versus cancerous cells.
Option 1: 'Cancerous cells have fewer divisions per hour initially but increase over time.' The data at time 0 shows equal starting counts (100 vs 100), and over time the cancerous cells increase to 173 while non-cancerous rise only to 115. This option suggests cancerous cells start lower, which isn’t supported; they start at the same level and quickly outpace non-cancerous cells.
Option 2: 'Both cell types have the same number of divisions per hour.' If we compare the numbers after each hour, cancerous cells are consistently higher (120 vs 105, 144 vs 110, 173 vs 115), so the two trajectories do not have the same rate. Therefore this statement is inaccurate.
Option 3: 'Cancerous cells consistently have more divisions per hour than non-cancerous cells.' Looking across all time points, the cancerous counts exceed the non-cancerous counts at hours 1, 2, and 3 (120>105, 144>110, 173>115). That pattern demonstrates a persistent difference with cancerous cells dividing more rapidly at each measured time point.
Option 4: 'Non-cancerous cells have more divisions per hour than cancerous cells.' The hourly comparisons show the opposite in every measured time point after 0 hours, so this statement conflicts with the observed data.
To interpret the trend, focus on the trajectory of the cancerous line versus the non-cancerous line: cancerous cells rise more steeply, indicating consistently higher division rates throughout the observed period. The non-cancerous cells increase too, but at a slower pace, maintaining a lower count at each subsequent hour.
In summary, the data depict a clear pattern where cancerous cells divide more rapidly than non-cancerous cells across the observed time points, while both lines show an upward trend with time, with the cancerous line remaining above the non-cancerous line at every measured interval.
