Question

During which periods did the patient's temperature showed an upward trend?

• A. 9 a.m. to 10 a.m., 10 a.m. to 11 a.m., 2 p.m. to 3 p.m.
• B. 9 a.m. to 10 a.m., 10.30 a.m. to 11.30 a.m., 2 p.m. to 3 p.m.
• C. 9 a.m. to 10 a.m., 10 a.m. to 11.30 a.m., 1 p.m. to 2 p.m.
• D. 9 a.m. to 10 a.m., 10 a.m. to 11 a.m., 1 p.m. to 2 p.m.

Answer 1

The correct option is A 9 a.m. to 10 a.m., 10 a.m. to 11 a.m., 2 p.m. to 3 p.m.

Whenever there is an increase in the value of $y-axis$ as the time(on $x-axis$) passes by, there is an upward trend.
Thus, the patient shows an upward trend between $9am-10am$, $10am-11am$ and $2pm-3pm$

Hence, option A is correct.
