Answer:The technique use in this study is referred to as a double blind
Explanation:
A double blind study is the one that both participants and experimenters or researchers are not made aware who is given a certain treatment.
In double blind researchers will not know if what they are receiving is part of the test itself as they interact with participants or they are receiving a placebo.
This process is useful to eliminate and avoid bias results.
For example, in the above text the effect of caffein on attention is being tested so the researchers will not know whether the drink given to them is actual for the test or just the placebo , they don't know who is in control of the experiment.

The answer is that <span>healthy </span>legs<span> have </span>veins<span> with smooth, elastic walls that </span>are<span> perfectly designed to </span>adapt<span> to the changes in pressure within a </span>vein<span>. </span>Veins<span> have </span>valves<span> that keep blood moving in one direction: back toward the heart. As the </span>leg<span> muscles </span>are<span> activated, the </span>venous valves<span> open to </span>allow<span> one-way flow in the direction of the heart.</span>
Answer:
Kafka gives no indication as to what may have caused Gregor's transformation.
Explanation:
Although we can interpret what Gregor's transformation represents, we have no indication of what caused it, since the author left no factor expressed in the narrative, probably to stimulate our interpretation of Gregor's dehumanization in the midst of capitalism and the exploitation he went through. Gregor's family and himself, see transformation as a random occurrence, something of chance, as a disease.
Unlikely, but it could happen
