The line graph shows the outdoor temperature every 2 hours, from hour 0 to hour 10. By how much Δ did the value change from hour 2 to hour 10? Use a negative number for a decrease.
The pie chart shows how a hospital’s 240 employees are split between departments A to E. How many employees x work in department A?
Where does the spinal cord normally end in an adult?
Injury to the common fibular (peroneal) nerve at the neck of the fibula typically causes:
Low plasma albumin, as in severe liver disease, causes oedema mainly because:
In a patient with primary hypothyroidism, you would expect:
What does RNA polymerase do?
To find out how much adults in a city exercise, a researcher surveys only people leaving a gym. What is the main problem?
Which compound is formed between calcium (Ca²⁺) and chlorine (Cl⁻)?
Which list puts 0.1 M solutions of HCl, acetic acid (CH₃COOH) and NaCl in order of increasing pH?
Which sentence avoids an unnecessary comma?
What is the function of the underlined word? “Swimming is good exercise for the heart.”
Choose the meaning of the word in bold: “The mortality rate from the disease has fallen.”
Which word means “indigestion, or discomfort in the upper abdomen after eating”?
Answer: C · First person, by a narrator who observes
The narrator uses “I” and shares their own thoughts while watching Mrs. Grey, so it is first person told by an observer. We never get Mrs. Grey’s own thoughts.

Answer: Δ = −2 °C
Reading charts and tables: read the title, the categories and the scale first. On a bar chart or line graph, follow the top of the bar or the point across to the vertical axis; every gridline is one step of the scale. A pie chart shows parts of a whole: a sector of p% stands for p% of the total and has an angle of p% of 360°.
Answer: x = 96

Answer: B · At about the level of vertebrae L1–L2
In adults the cord ends at the conus medullaris near L1–L2. Below that lies the cauda equina, which is why lumbar punctures are done at L3–L4 or L4–L5.

RNA polymerase binds near the start of a gene, unwinds the DNA and joins RNA nucleotides that are complementary to the template strand. Translation into protein happens later on ribosomes.
Answer: C · The sample is biased towards active people
Gym-goers exercise more than the average adult, so the sample overestimates exercise. A random sample of the whole population would be better.
Answer: C · CaCl₂
One Ca²⁺ needs two Cl⁻ ions to balance the charges: (+2) + 2 × (−1) = 0, giving CaCl₂.
Answer: A · HCl < CH₃COOH < NaCl
At equal concentrations, the strong acid HCl releases the most H⁺ (lowest pH), weak acetic acid releases fewer, and NaCl is a neutral salt with a pH near 7.
Answer: C · The patient in room 4 needs a new IV bag.
“The patient in room 4” is the full subject, and nothing should separate it from the verb “needs”.
