1. The author's primary purpose in the passage is to
The primary purpose of the passage is to discuss/ascertain whether cell phone radiations pose health risk in the levels in which they are absorbed
This can be seen in the last line of 1st para
Quote:
There is no doubt that the body absorbs varying levels of radiation emitted by cell phones, but the question is, do these levels pose a health risk?
In the following paragraphs, the author does express her opinion in a few instances (such as by calling a statement made by FCC vague), but the primary purpose is to address whether cell phone use is unhealthy not just express her view on radiations.
A. dispel rumors about the negative side effects of cell phone use
Incorrect. Not trying to dispel any rumorsB. illustrate how the risks associated with using a cell phone outweigh the phone's positive uses
Incorrect. No mention of positive usesC. describe how cell phones transmit voice data and other information
Incorrect. This is just one line of para 2, whole passage is not concerned with how this is doneD. discuss her personal views on the subject of cell phone radiation
Incorrect for the reason stated aboveE. address the question of whether or not cell phone use is unhealthy
Correct2. It can be inferred from the passage that a phone deemed "safe" (Highlighted) by the FCC would actually be better described as
A. probably safe
Incorrect. probably expresses the likelihood or high chances of something happening, but in this case we express doubtB. possibly safe
Correct. Possibly means maybe or perhaps and is thus, used when there is no suretyC. completely safe
Incorrect. the passage continues by saying that the statement is misleadingD. somewhat dangerous
Incorrect. No hard evidence of adverse effect has been foundE. extremely dangerous
Incorrect. Extreme is out of scope3. According to the passage, which of the following is true?
A. Cell phone batteries utilize the power of RF energy.
Incorrect. cell phones emit itB. The FCC would consider a cell phone with a SAR level of 1.5 W/kg as unsafe.
Incorrect. they deem it as safeC. Henry Lai concluded that the exposure of rats to RF energy could be linked to cancer and brain tumors in rats.
CorrectD. The FDA and FCC believe that further cell phone research is unnecessary
Incorrect. On the contrary they ask for further researchE. Smaller cell phones have higher SAR ratings.
Incorrect. No mention of cell hone size4. According to information from the passage, it can be inferred that which of the following devices also emit RF energy?
Quote:
Mobile phones employ radio waves, more specifically, radiofrequency (RF) energy, to wirelessly transmit voice data and other information between handsets and base stations.
A. a standard wall phone
Incorrect. not wirelessB. a television broadcast tower
Correct. It emits radiationsC. a DVD player
Incorrect. not wirelessD. a radio speaker
Incorrect. It receives radiationE. an internet router
Incorrect. It receives radiation5. The author most probably notes (Highlighted) that "one of the studies that tried to confirm Lai's findings was conducted by a group funded by the cell phone manufacturer Motorola" to suggest
A. a possible bias on the part of the confirmation group
CorrectIt expresses an idea as to why a cellphone co. would want to prove that phones emit radiations harmful to health. Wouldn't that negatively affect their businessB. that Lai was a disgruntled ex-employee of Motorola
IncorrectC. Cell phone manufacturers are actively trying to sabotage radiation research
Incorret. Only 1 of the studies is mentioned. We don't know about othersD. that Motorola is looking for alternatives to RF energy
Incorrect. Can't be inferredE. Lai's research team lied about their findings
Incorrect. Can't be inferred6. The author draws a comparison between cigarettes and cell phones in the final sentence of the passage in order to
A. illustrate a historical precedent
Correct. We got confirmation of the evidence that smoking is unhealthy rather lateB. demonstrate how quickly a person becomes hooked on their phone
Incorrect. Addiction is not the concernC. display her dislike for both
Incorrect. Nothing of this sort has been expressedD. make a point about social etiquette
Incorrect. Nothing about social etiquetteE. exaggerate the issue to help her illustrate a point
Incorrect. Author is just stating a fact, not exaggerating
