Answer:





Explanation:
Required
Evaluate each expression
The simple rules to follow are:
(1) All expressions in bracket will be evaluated based on its data type
(2) Divisions will return only integer values
(3) Integers immediately after string values will be concatenated (not added)
So, the results are as follows:

Evaluate till a string is encountered

Followed by "."
Then:

-- because expressions after string operations are concatenated.
So, we have:


Evaluate till a string is encountered


So, we have:


Evaluate till a string is encountered


So, we have:
Evaluate till a string is encountered

--- multiply 2 and 3, then concatenate
So, we have:


Since a string starts the expression, the whole expression will be concatenated except the multiplication and the expressions in bracket.
So, we have:

Answer:
It is supported by many different experiments.
Explanation:
Scientific theory is based on different experiments and tested in different situations and environment will all aspects. If the experiment finds true then observations will become theory. It can be changed in future if it does not meet the newly proposed conditions. But It does not means that, every theory can be changed.
