Answer:
At different times
Explanation:
The echo returns at different times, but faster in water. This is because water particles are bound closer and this makes them transmit vibration energy from one particle to the next quickly. An echo is a sound wave and sound waves are longitudinal waves that occur by the collision of particles to move the vibrations along, and this is why they move slower in air.
Shelly provides multiple perspectives (narrative shift) throughout three volumes of the same story. In each of these volumes, you learn the perspective of Walton, Frankenstein, and Adam (AKA the creature). This allows the reader to develop for themselves who they believe is guilty and come up with their own interpretation of the story. This allows for a more reliable narration because if only one perspective is given, how would you know they weren't just lying or giving a bias interpretation?
Answer:
valid.
Explanation:
Valid is something effective, legally binding or able to withstand objection.
In deductive reasoning, an argument is valid if and only if it takes a form that makes it impossible for the premises to be true and the conclusion nevertheless to be false. It is not required for a valid argument to have premises that are actually true, but to have premises that, if they were true, would guarantee the truth of the argument's conclusion. Valid arguments must be clearly expressed by means of sentences called well-formed formulas. The validity of an argument can be tested, proved or disproved, and depends on its logical form.
An argument is a set of statements expressing the premises and an evidence-based conclusion.
