They have very sharp teeth to cut through their prey, or try to escape if they are trapped
Their bodies are very narrow, enabling them to be very quick and nimble, it also enables them to hide it tight spaces
Their teeth also enables them to escape a fishermen's line ( I'm a fishermen and I've lost many barracuda due to those teeth.)
I hope this helped
With smelly feet, you can avoid people who are boring and dangerous (,like bullies),
Greenhouse gas emissions will continue to increase in the short term, but as new technologies are discovered and implemented by governments and industries, this may eventually reverse. Global climate may continue to warm, but once greenhouse gas emissions are lowered, this may slowly reverse. Current solutions are not yet enough to stop the increase in temperature, but some technologies on the horizon are promising, such as carbon capture and storage, solar energy, and aquaculture of biofuels. One immediate way to reduce greenhouse gas emissions is a change in lifestyle, for example, using less fuel-intensive transportation options and saving electricity.
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.
