There are different factors taken into consideration in production process. The statement that best justifies the use of the proposed modification as a way of creating an appropriate control for the investigation is that;

  • The experiment can be repeated without the use of guaiacol, which will therefore show the effect of guaiacol on the reaction rates.

Oxygen is an element that exist naturally and can also be produced from different kinds of materials. This is often done by using a lot of different methods.

The natural method of getting oxygen is through photosynthesis where plants are known to use sunlight to convert carbon dioxide in the air into oxygen.

By not using guaiacol again when repeating the same experiment, one can therefore know if the guaiacol in one or different ways affect the chemical reaction of the elements.

Answer:

<h3>Plessy v. Ferguson case.</h3>

Explanation:

  • The Plessy v. Ferguson case of 1896 ruled out that segregation was constitutional as long as both blacks and whites enjoyed opportunities that were separate but equal.
  • However, the Supreme Court's verdict in the Plessy v. Ferguson case of 1896 was challenged by Justice Earl Warren stating that the idea of ‘separate but equal’ in public school was unconstitutional and inherently unequal.
  • Thus, Chief Justice Earl Warren issued the Supreme Court’s unanimous decision in Brown v. Board of Education, ruling that racial segregation in public schools violated the "Equal Protection Clause” of the 14th Amendment.

How does the speaker’s repetition of the neighbor’s cherished belief about the importance of walls (lines 27 and 45) convey the
dolphi86 [110]

The way in which the speaker’s repetition of the neighbor’s cherished belief about the importance of walls conveys the poem’s criticism of an undesirable social pattern is that;

The speaker treats the neighbor’s words about fences as evidence of a worldview that is closed-minded in general.

This question is drawn from a poem titled "Mending Wall" written by Robert Forst in the 20th Century.

  • The major theme of the poem is the self imposed barriers that prevent human interaction. This was illustrated by the speaker's neighbor who kept on rebuilding a wall that was not required. This was because it didn't benefit anyone and as such the fence was harmful to their land.

  • While speaking about the neighbors cherished belief of fence walls in lines 27 and 45, the speaker treats the neighbor’s words about fences as an evidence of him having a worldview that is largely closed-minded.
