Two people, P and Q, each have a drink containing glucose at 0 minutes.
Their blood glucose concentration is then measured every 30 minutes.
Table
| Time in minutes | 0 | 30 | 60 | 90 | 120 |
|---|---|---|---|---|---|
| Person P blood glucose in mg/100 cm3\text{mg}/100\ \text{cm}^3mg/100 cm3 | 90 | 140 | 120 | 95 | 90 |
| Person Q blood glucose in mg/100 cm3\text{mg}/100\ \text{cm}^3mg/100 cm3 | 130 | 220 | 260 | 250 | 230 |
Which conclusion is supported by the data?
Person Q does not have diabetes, because their blood glucose rises highest.
Person P has diabetes, because their blood glucose rises after the drink.
Person P has diabetes, because their blood glucose returns to its start level.
Person Q has diabetes, because their blood glucose stays high for longer.
