1. In the sentence "The house was dilapidated," what effect does the word "dilapidated" have on the reader's understanding?

• A. Creates a sense of mystery.
• B. Emphasizes the large size of the house.
• C. Suggests the house is in poor condition.
• D. Implies the house is haunted.

Correct answer: C

Rationale: The word "dilapidated" specifically describes the house's deteriorating state.

2. A table shows the blood pressure readings for different age groups. How do you determine the patient with the highest systolic pressure?

• A. Find the largest number in the "systolic pressure" column.
• B. Compare the means (averages) of each age group.
• C. Add all systolic pressure values and divide by the total number of patients.
• D. Subtract the lowest systolic pressure from the highest.

Correct answer: A

Rationale: The best way is to compare the average systolic pressure values for each age group to identify the highest.

3. You need to repaint a cylindrical water tank with a diameter of 2 meters and a height of 3 meters. Assuming one can of paint covers 10 sq m, how many cans do you need (consider only the exterior surface)?

• A. 6 cans
• B. 9 cans
• C. 12 cans
• D. 15 cans

Correct answer: C

Rationale: Calculate the surface area of the cylinder and divide by the coverage area per can.

4. What does the term "net force" refer to in physics?

• A. Total force acting on an object
• B. Force due to gravity
• C. Force in motion
• D. Force of friction

Correct answer: a

Rationale: Net force is the vector sum of all forces acting on an object.

5. Which part of the heart generates the QRS complex on an ECG?

• A. Sinoatrial node (SA node)
• B. Atrioventricular node (AV node)
• C. Bundle of His
• D. Ventricular muscle cells

Correct answer: D

Rationale: The correct answer is D, ventricular muscle cells. The QRS complex on an ECG represents the depolarization of the ventricles. This electrical activity is generated by the spread of impulses through the bundle branches and Purkinje fibers to the ventricular muscle cells. The SA node (option A) is responsible for initiating the electrical impulse in the heart, but it does not directly generate the QRS complex. The AV node (option B) delays the impulse to allow for proper coordination of atrial and ventricular contractions. The Bundle of His (option C) and its branches facilitate the conduction of the electrical signal from the AV node to the ventricles but do not generate the QRS complex directly.

6. Identify the incorrect usage of punctuation in the following sentence: "The children, eager to play, ran outside. It was a beautiful day."

• A. comma after "children"
• B. comma after "play"
• C. period after "outside"
• D. no errors

Correct answer: C

Rationale: The two sentences are independent clauses and should be separated by a semicolon or period, not a comma.
