It is very important for children to have quality time with their parents. Parents who provide this type of interaction may be assured of a bright future for their offspring. By the same token, according to a study by the Centers for Disease Control, parents who work do not have as much time to devote to parenting. Thus, working mothers automatically thrust an obstacle into their children's developmental future.
The argument in the passage illustrates the following component/s:

  1. faulty appeal to authority
  2. faulty application of cause and effect
  3. faulty initial premise
  4. faulty appeal to authority and faulty application of cause and effect

Answer(s): D

Explanation:

The Centers for Disease Control would not be an authority on parenting time. The author cannot assume that little time means little time with children. Therefore, both of these premises are faulty. The initial premise is not obviously faulty, just the information given in the passage.



(1) Fluorescent proteins are found in bioluminescent sea creatures, such as jellyfish. (2) In 1969, the green fluorescent protein was discovered and, since then, prolific research has resulted in the discovery and development of many new fluorescent proteins. (3) Fluorescent proteins can be expressed in cells, making them easily visible under a microscope. (4) In fact, the use of fluorescent proteins revolutionized bio-imaging because the inherently natural nature meant that they could be incorporated into living cells with no deadly toxic effects. (5) Numerous other scientific and medical applications also exploit the unique properties of fluorescent proteins, which is why they were the subject of the 2008 Nobel Prize for Chemistry. (6) However, the science behind fluorescent proteins is still not fully understood, and there are many more avenues for exploration.
If the author had intended to provide an overview of all the applications of fluorescent proteins, would this passage achieve that goal?

  1. Yes, the passage describes multiple applications.
  2. No, because the passage describes only one application in detail.
  3. No, the passage describes no applications.
  4. Yes, the passage describes one application.

Answer(s): B

Explanation:

The passage describes only one application and does not specifically mention any others.

What is implied by the fourth sentence of the passage?

  1. The discovery of fluorescent proteins was not important in the field of bio-imaging.
  2. Fluorescent proteins kill living cells.
  3. Bio-imaging in living cells has always been possible.
  4. Bio-imaging in living cells was not possible before the discovery of fluorescent proteins.

Answer(s): D

Explanation:

The sentence states that bio-imaging was revolutionized because fluorescent proteins could be put into living cells without deadly toxic effects. The word "revolutionized" is very powerful and the sentence implies that "deadly toxic effects" prevented bio-imaging in live cells before fluorescent proteins were discovered.

Which term might you suggest the author abbreviate in this passage?

  1. living cells
  2. sea creatures
  3. fluorescent protein
  4. microscope

Answer(s): C

Explanation:

The term fluorescent protein(s) is used 7 times in the passage and abbreviating it would help to make the passage more readable and more easily understood.
