How many different kinds of elements are there in the human body in all?
Think it through first, then pick an option.
- a 20
- b 26
- c 98
- d 118
Answer and explanation
Correct answer: b 26
The human body contains 26 different elements in all.
Why the other options are wrong
- a 20: 20 is not the count; the human body contains 26 different elements.
- c 98: 98 is the number of elements found in nature (the board count), not the number in the body; the body has 26 kinds.
- d 118: 118 is the number of all elements discovered so far; the human body holds 26 kinds among them.
