Technician: It is true that the Nebula G10 smartphone is not as valuable as the Outlook M1 smartphone because, on average, insurance companies do not pay as much to replace a lost Nebula G10 as to replace a lost Outlook M1. Repair costs show a different picture though. It can’t be denied that the repairs to Nebula G10 phones are especially labor-intensive and labor is a significant factor in accident repair costs. As a result, the average amount that insurance companies pay to repair a phone under warranty that is damaged by an accident is typically higher for the Nebula G10 than for the Outlook M1.

Which of the following, if true, most strongly supports the technician’s explanation?

A. Reliable statistics show that Outlook M1 phones are more frequently damaged in accidents than Nebula G10 phones are.
B. Outlook M1 phones are considered more economically valuable largely for the ease of repair of the phones.
C. Availability of technicians specializing in the repairs of Nebula G10 is higher than that of technicians specializing in the repairs of Outlook M1.
D. No significant difference exists between the cost of routine upkeep of Outlook M1 and that of Nebula G10.
E. Consumer data indicates that the Nebula G10 phones are returned for defects at a rate greater than that for Outlook M1 phones.

Forensic scientists trained to authenticate antiques do so by analyzing not only the physical form of the antique but also such properties as the chemical composition of the materials it is composed of and microscopic signs of damage that indicate its age. Even the most adept forgers cannot duplicate all of the properties the scientists analyze.

Which of the following can be logically concluded from the passage above?

A. The time it takes for the forensic scientists to examine an antique and determine its authenticity makes their services impractical for commercial use.
B. Nobody can secure authentication from a forensic scientist trained to authenticate antiques by relying solely on a skill for forging antiques.
C. Forensic scientists trained to authenticate antiques will soon be hired by most museums.
D. Forensic forgery-detection training has taken many years to formulate and perfect.
E. In many cases even genuine antiques are denied authentication by forensic scientists trained to authenticate antiques.

CR 1

The introduction of ladybugs into a garden ecosystem is an excellent method of protecting ornamental flowers from aphids. Unfortunately, the ladybugs will only prey on the aphids for a week before flying away, and no aphid infestation severe enough to warrant the deployment of ladybugs can be cleared in a single week. However, although synthetic pesticides are not much longer lasting, they can be easily reapplied whenever the aphids reappear. Clearly, therefore, for protecting ornamental flowers from aphids, introducing ladybugs can play no useful role.

The argument is most vulnerable to the objection that it fails to

A. consider that there might be less severe aphid infestations that can be cleared in a week
B. allow for the possibility of combining the two aphid-control methods it mentions
C. distinguish among the several varieties of synthetic pesticides
D. mention any alternative aphid control method that could be utilized in place of the rejected method
E. allow for the possibility that the introduction of insects other than ladybugs might have the same effect.

Environmentalist: Cod prices in our area need to be increased significantly. The cod population in the nearby ocean has been falling for years because cod is being fished at unsustainable levels. Due to the low price of cod, few consumers have been affected by the introduction of the hefty environmental tax on the sale of this endangered fish.

The two sections in boldface play which of the following roles in the environmentalist’s argument?

(A) The first is a conclusion that the argument provides support for, and which in turn provides support for the main conclusion; the second is the main conclusion.
(B) The first is the only conclusion; the second provides an explanation for the first.
(C) The first is an observation that the second provides an explanation for; the second is the main conclusion but not the only conclusion.
(D) The first is a premise that supports the main conclusion of the argument; so is the second.
(E) The first is the main conclusion; the second is a conclusion supported by the argument, and which in turn supports the first.
