Field - i think , it just makes the most sense
A balanced budget is all about not going over or too low. If you can keep the budget to a minimum but not too low then your budget would be balanced. You want to have at least the same amount of money in your pocket than what you are going to spend.
In natural experiments, the researcher compares groups exposed or not to exogenous agents, but does intervene in group composition or independent variable modification. This is a natural experiment.
<h3>
What is a natural experiment?</h3>
There are two types of investigation strategies,
- Manipulative investigation
In a natural experiment the researcher does not intervene in the creation of treatment and control groups.
There is an exogenous agent, such as a natural phenomenon, that influences the study groups and that acts as the treatment.
The researcher takes advantage of these events to use these random groups to compare them in the study.
The researcher chooses exposed groups (experimental groups) that might have been affected by the natural event and other groups that have not been affected (control groups).
In the exposed example,
- Exogenous agent ⇒ Treatment ⇒ pesticide use
- Exposed group ⇒ Experimental group ⇒ birds from nests in pesticide-sprayed fields
- Not exposed groups ⇒ Control groups ⇒ birds from nests in unsprayed fields.
Since the researcher does not voluntarily modify the independent variable to observe a response in the dependent variable, this experiment could not be considered to be manipulative.
This is an example of a natural experiment in which the researcher chooses groups exposed to different conditions to compare them and analyze the effect of the pesticide.

Answer;
It is impossible to tell from the data provided.
Explanation;
Different animals can be categorized as either protostomes and deuterostomes based on certain features of their embryonic developments.
For those categorized as protostome; the features include; mouth from blastopore, spiral,determinate cleavage, and coelom from solid masses of mesoderm
Those categorized as deuterostome have features such as coelom from folds of archenteron, radial, indeterminate cleavage, and anus from blastopore.
