Answer:
The correct answer is - D) reactive.
Explanation:
As a result of the reactivity phenomenon, individuals who are aware that they are being observed, alter their behavior (react) in such a way that in their opinion will satisfy the observer.
Here, Cruella thinks that people are expected to care about animal rights (‘because it is a good thing’), and though she actually does not, she responds (reacts) that she does - for the therapist not to think bad of her.
This phenomenon often obscures collected data that undermines studies’ validity. In particular, unobtrusive research methods, where the researcher finds indirect ways to obtain necessary data (for example, via collecting anonymous data) is one of the ways to tackle this issue.
The secret agreement with France and Spain affected American settlers which became
known as the Louisiana Purchase.
Answer: The scientific method provides a systematic approach for testing hypotheses, even when it is not possible to use several different groups. In such cases, scientists can make use of other experimental techniques to evaluate their hypotheses. Here are a few possible methods:
1. Controlled experiments with repeated measurements: The scientist can design an experiment where a single group is exposed to different conditions or treatments. The measurements or observations are then repeated multiple times to ensure reliability. By comparing the results from the different conditions or treatments, the scientist can analyze the data and draw conclusions about the hypothesis.
2. Comparative studies: Instead of having multiple groups, the scientist can compare different variables or factors within a single group. For example, if the hypothesis is about the effect of temperature on plant growth, the scientist can expose the same group of plants to different temperature levels and measure their growth over time. By comparing the growth of the plants under different temperature conditions, the scientist can evaluate the hypothesis.
3. Observational studies: In situations where experimental manipulation is not feasible, scientists can conduct observational studies. They can collect data by observing natural phenomena or existing conditions. For example, if the hypothesis is about the impact of air pollution on respiratory health, the scientist can analyze existing data from areas with different levels of air pollution and compare the rates of respiratory illnesses.
4. Simulation or modeling: When conducting experiments is not practical or ethical, scientists can use computer simulations or mathematical models to test their hypotheses. They can input data and parameters into the simulation or model and observe the predicted outcomes. This allows them to assess the validity of their hypothesis in a virtual environment.
Remember, the specific method chosen will depend on the nature of the hypothesis and the available resources. Scientists must carefully design their experiments, collect and analyze data, and draw conclusions based on the evidence obtained.
