A certain type of prehistoric basket has been found in only two locations, one on private property and the other on a protected archaeological site. An electron microscope was used to examine one such basket. Unless an artifact has been thoroughly cleaned, an electron microscope will detect on the artifact minerals characteristic of the soil of the site where the artifact was excavated. Yet no minerals characteristic of the soil of the protected site were detected on the basket, although the basket was still encrusted with soil from the site from which it had been excavated.
The information in the passage, if correct, most strongly supports which one of the following?
(A) The basket was excavated on private property.
(B) The basket was excavated on the protected site.
(C) The basket was too encrusted with soil to be examined accurately.
(D) No minerals characteristic of the soil of the private site were detected on the basket.
(E) Some minerals characteristic of the soil of the protected site are also contained in the soil of the private site.

A certain type of prehistoric basket
has been found
_____in only two locations,
__________one on private property
__________and the other on a protected archaeological site.
An electron microscope
was used
_____to examine one such basket.
Unless an artifact has been thoroughly cleaned,
an electron microscope will detect on the artifact minerals characteristic
_____of the soil
__________of the site
_______________where the artifact was excavated.
Yet no minerals characteristic
_____of the soil
__________of the protected site were detected on the basket,
although the basket
was still encrusted with soil from the site
_____from which it had been excavated.
Step1: Argument or Fact set? --> Fact set
Step2: Check Conditional/ Causal Statements --> Found the Condition Statement (Indicator: Unless)
Necessary Condition: C == Unless an artifact has been thoroughly cleaned,
Sufficient Condition: D == an electron microscope will detect on the artifact minerals characteristic of the soil of the site where the artifact was excavated.
D --> C && C --> D
Step3: Question Stem: Must be True
--> expect 2 types of correct answers: 1) Paraphrase 2) Combination of Premises
--> expect 5 types of incorrect answers: 1) Could be True 2) Exaggerated Answer 3) New Information 4) Shell Game 5) Opposite 6) Reverse
Step4: 5 Answer Choices:
A. Noted that "Yet no minerals characteristic of the soil of the protected site were detected on the basket" --> only 2 possibilities:
1) The artifact has been thoroughly cleaned --> This one is rejected by the information: "the basket was still encrusted with soil from the site from which it had been excavated"
2) The basket was NOT excavated on the protected property; Plus, since we have "A certain type of prehistoric basket
has been found in only two locations" --> we can infer that The basket was excavated on private property.
--> A is the correct Answer
B. This is the Opposite Answer --> Wrong
C. New information: "too encrusted with soil to be examined accurately" --> Wrong
D. New information: "No minerals characteristic of the soil of the private site were detected on the basket."
E. New information: "Some minerals characteristic of the soil of the protected site are also contained in the soil of the private site."
