The dominant modern belief is that the soundest foundation of peace would be universal prosperity. One may look in vain for historical evidence that the rich have regularly been more peaceful than the poor, but then it can be argued that they have never felt secure against the poor; that their aggressiveness stemmed from fear; and that the situation would be quite different if everybody were rich.

It can be inferred from the above passage that

Answer the question based on the passage given below.

A food chain is somewhat a linear sequence of links in a food trophic species that eats no other species in the web and ends at a trophic species that is eaten by no other species in the web. A food chain differs from a food web, because the complex polyphagous network of feeding relations are aggregated into trophic species and the chain only follows linear monophagous pathways. A common metric used to quantify food web trophic structure is food chain length. In its simplest form, the length of a chain is the number of links between a trophic consumer and the base of the web and the mean chain length of an entire web is the arithmetic average of the lengths of all chains in a food web.

Which of the following can be concluded from the passage?
    1. You can calculate the length of a food chain by calculating the average length of all the chains.
    1. Food chains and food webs differ from one another in the sense that food webs are more complex.You can calculate the average length of a food web by adding the lengths of all the links and then dividing them by the total number of the links.
    1. You can calculate the length of a food web by adding the lengths of all the links in the web.
    1. If a tiger and a zebra were in the food chain, a lion would be at a higher position than the zebra.
    1. Food chains and food webs differ from one another in the sense that the former is more complex.

Historians continue to debate the number of Indian warriors participating in the battle. They estimate that in the overall battle, the warriors outnumbered the 7th Cavalry by approximately three to one, or roughly 1,800 against 600. In Custer's fight, this ratio could have increased to as high as nine to one (1,800 against 200) after his isolated command became the main focus of the fighting. Some historians, however, claim the ratio of the Custer fight to be as low as three to one. Custer's detachment was certainly outnumbered and was caught in the open on unfamiliar terrain. Within weeks of the battle, the public estimate by whites of the number of Indian warriors rapidly increased. For example, in a letter to his wife dated soon after the battle, Benteen indicates 3,000 Indians; his later estimates were much higher. Some recent research points to a force of Indians much closer in size to Custer's own, however.
Which of the following can be concluded from the passage?

  • The number of people in Custer's cavalry and the number of Indians he was fighting against were the same.
  • There is no doubt that the number of Indians was much higher than that of the whites.
  • The number of Indian warriors that participated in the battle was a matter of great confluence.
  • There was a certain amount of significance attached to the number of Indian warriors participating in the battle.
  • Indians outnumbered and outranked the whites.

Although aspirin has been proven to eliminate moderate fever associated with some illnesses, many doctors no longer routinely recommend its use for this purpose. A moderate fever stimulates the activity of the body's disease-fighting white blood cells and also inhibits the growth of many strains of disease-causing bacteria.

Last year all refuse collected by Shelbyville city services was incinerated. This incineration generated a large quantity of residual ash. In order to reduce the amount of residual ash Shelbyville generates this year to half of last year’s total, the city has revamped its collection program. This year city services will separate for recycling enough refuse to reduce the number of truckloads of refuse to be incinerated to half of last year’s number.

Which of the following is required for the revamped collection program to achieve its aim?

No OA. Please discuss

  • Separating recyclable materials from materials to be incinerated will cost Shelbyville less than half what it cost last year to dispose of the residual ash.
  • This year, no materials that city services could separate for recycling will be incinerated.
  • The total quantity of refuse collected by Shelbyville city services this year will be no greater than that collected last year.
  • The refuse incinerated this year will generate no more residual ash per truckload incinerated than did the refuse incinerated last year.
  • Refuse collected by city services will contain a larger proportion of recyclable materials this year than it did last year.
