Question is which is NOT a good technique.
Answer is "B" and here's why:
A) Clear questions -- good. People understanding the question will answer accurately.
C) Large sample size -- good. Answers will be more accurate with more people asked (like if you flip a coin 1,000 times its going to be closer to 50% heads than if you only flipped it twice)
D) Random sample -- good. Avoids your own bias in choosing who to ask.
B) Push poll -- bad. Pretends to be unbiased, the pollster's real objective is to get a person thinking in a way that is to their advantage. Some political candidates do this just before elections.

Answer:
#Mitral valves
There is a valve at the meeting point between each ureter and the bladder to prevent the backflow of urine into the kidneys.
Urinary reflux means that one (or both) of these valves is not working properly.
If you have urinary reflux, during urination the urine travels up the affected ureter to the kidney instead of flowing out of the body.
Urinary reflux most commonly occurs in babies and children.
In most cases, the valve will correct itself as a child grows and matures.
In severe cases, surgery may be needed to remodel the valve.
#Urine flows from each kidney through tubes called ureters and into the bladder. When the bladder is full, it squeezes and sends the urine out through the urethra. No urine should flow back into the ureter when the bladder is squeezing. Each ureter has a one-way valve where it enters the bladder that prevents urine from flowing back up the ureter.
