Answer:
In studies about new medicines, researchers usually give one group of patients the medicine that is designed to treat an illness. They give another group of patients a placebo, which is taken the same way as the medicine but does not actually contain the ingredients of any medicine. Different medicines are tested in different experiments, but the placebos usually contain the same non-medical ingredients. If both groups of patients are healed, then researchers cannot be sure whether the medicine caused improvement, but if the group given the medicine is healed while the group given the placebo remains ill, researchers can conclude that the medicine causes the illness to go away.
In medical experiments, which group receives placebos?
the experimental group
the control group
both the experimental and control groups
neither the experimental nor control group

This idea is popularly called WORA that is Write Once Run Anywhere.

Available options
=A4&&B4
=A4&" "&B4
="A4"&""&"34"
=A4&""&B4
Answer:
=A4&""&B4
Explanation:
In a Microsoft Excel spreadsheet, to combine the content of two cells into another cell, a user will have to use the command &
Hence, in this case, given that there is no need to have any character or blank space in between the content of the starging cells, which is just A4 and B4, then we have the following technique
1. Select the cell C2
2. Input the command = or +, then select cell A4
3. Input the command &
4. Then select the cell B4
5. Click enter.
Therefore, the answer should appear as =A4&B4.
But from the available options, there is nothing like that, so we pick =A4&""&B4 because it gives the same outcome.
SQL (<span>Structured Query Language.) is the standard programming language for communicating and organizing databases (DB).
In order to search through the database the statement SELECT should be used.
SELECT select data from the database.
SELECT is followed by the statement FROM which defines from which database you search record. </span>
