Answer:

Some would argue deductive reasoning is an important life skill. It allows you to take information from two or more statements and draw a logically sound conclusion.

Step-by-step explanation:

Deductive reasoning is a type of deduction used in science and in life. It is when you take two true statements, or premises, to form a conclusion. For example, A is equal to B. B is also equal to C. Given those two statements, you can conclude A is equal to C using deductive reasoning.

Now, let’s look at a real-life example.

  • All dolphins are mammals.
  • All mammals have kidneys.

some more examples

  • Everyday life often tests our powers of deductive reasoning. Did you ever wonder when you'd need what you learned in algebra class?
  • Well, if nothing else, those lessons were meant to stretch our powers of deductive reasoning. Remember, if a = b and b = c, then a = c. Let's flesh that out with added examples:
  • All numbers ending in 0 or 5 are divisible by 5. The number 35 ends with a 5, so it must be divisible by 5.
  • All birds have feathers. All robins are birds. Therefore, robins have feathers.
  • It's dangerous to drive on icy streets. The streets are icy now, so it would be dangerous to drive on the streets.
  • All cats have a keen sense of smell. Fluffy is a cat, so Fluffy has a keen sense of smell.
  • Cacti are plants, and all plants perform photosynthesis. Therefore, cacti perform photosynthesis.
  • Red meat has iron in it, and beef is red meat. Therefore, beef has iron in it.
  • Acute angles are less than 90 degrees. This angle is 40 degrees, so it must be an acute angle.
  • All noble gases are stable. Helium is a noble gas, so helium is stable.
  • Elephants have cells in their bodies, and all cells have DNA. Therefore, elephants have DNA.
  • All horses have manes. The Arabian is a horse; therefore, Arabians have manes.
