While researching a topic, a student has taken the following notes:

  • Dr. Sunil Bajpai studies dinosaurs at the Indian Institute of Technology.
  • Bajpai's research team recently found a 167-million-year-old dicraeosaurid fossil.
  • It is the oldest fossil from the dicraeosaurid dinosaur group ever recovered.
  • It was found in the Thar Desert in western India.

The student wants to indicate where the dicraeosaurid fossil was found. Which choice most effectively uses relevant information from the notes to accomplish this goal?

A
The dicraeosaurid fossil was found in western India's Thar Desert.
B
Bajpai's team recently found the oldest dicraeosaurid fossil ever recovered.
C
Dr. Sunil Bajpai, of the Indian Institute of Technology, is part of a research team.
D
The fossil, which is from the dicraeosaurid dinosaur group, is 167 million years old.
Solution

Step 1: Decode and Map the Passage

Part A: Create Passage Analysis Table

Text from PassageAnalysis
"Dr. Sunil Bajpai studies dinosaurs at the Indian Institute of Technology."
  • What it says: Dr. Bajpai = dinosaur researcher @ IIT
  • What it does: Introduces the researcher and his affiliation
  • What it is: Background context
"Bajpai's research team recently found a 167-million-year-old dicraeosaurid fossil."
  • What it says: Bajpai's team found 167M yr old dicraeosaurid fossil
  • What it does: Presents the main discovery
  • What it is: Main finding
"It is the oldest fossil from the dicraeosaurid dinosaur group ever recovered."
  • What it says: oldest dicraeosaurid fossil ever
  • What it does: Explains the significance of the discovery
  • What it is: Significance statement
"It was found in the Thar Desert in western India."
  • What it says: Location = Thar Desert, western India
  • What it does: Provides the geographic location of the discovery
  • What it is: Location information

Part B: Provide Passage Architecture & Core Elements

  • Main Point: Dr. Bajpai's research team discovered a record-breaking 167-million-year-old dicraeosaurid fossil in western India's Thar Desert.
  • Argument Flow: The notes establish the researcher's credentials, then present the key discovery, and conclude by highlighting both its scientific significance and geographic origin.

Step 2: Interpret the Question Precisely

What's being asked? Which choice most effectively indicates where the dicraeosaurid fossil was found.

What type of answer do we need? A statement that clearly communicates the location information from the notes.

Any limiting keywords? "most effectively uses relevant information from the notes" - so we need to use the actual location details provided.

Step 3: Prethink the Answer

  • The right answer should directly state where the fossil was found using the specific location information from the notes: "Thar Desert in western India" and should focus on location rather than other aspects like age, significance, or researcher details.
Answer Choices Explained
A
The dicraeosaurid fossil was found in western India's Thar Desert.
  • Directly states the location using exact geographic information from the notes and accomplishes the stated goal of indicating where the fossil was found
B
Bajpai's team recently found the oldest dicraeosaurid fossil ever recovered.
  • Focuses on the fossil being the oldest ever recovered with no location information
C
Dr. Sunil Bajpai, of the Indian Institute of Technology, is part of a research team.
  • Focuses on Dr. Bajpai's institutional affiliation with no information about fossil location
D
The fossil, which is from the dicraeosaurid dinosaur group, is 167 million years old.
  • Focuses on the fossil's age and type classification with no geographic information
