While determining which antibiotics are best to treat ulcers caused by helicobacter pylori, the drugs used in the experiment are called the: B. experimental variable.

<h3>What is an experiment?</h3>

An experiment can be defined as a scientific investigation which typically involves the process of manipulating an independent variable (the cause), so as to determine or measure the dependent variable (the effect).

<h3>What is an experimental variable?</h3>

In Science, an experimental variable can be defined as a measurable attribute or physical quantity that changes or varies across an experiment and as such can take on different numerical values.

In this context, we can reasonably infer and logically deduce that the drugs used in this experiment are called the experimental variable.

solong [7]
This is a question with a much simpler answer given its open ended ness - a representation merely means, given binary data, we can determine what 'thing' that binary data corresponds to.

<span>That makes the question unanswerable, because words can all be represented in binary data, and the question cannot be answered without those. Thus, all answers we can convey have a binary representation of some form (that form being the translation of the words we used to communicate the answer into binary data).</span>

I didn't implement the functions because the problem never stated that we had to. Best of luck.
