Question

Match LIST-I with LIST-II 

Choose the correct answer from the options given below: 
 

• A. A-I, B-II, C-III, D-IV
• B. A-I, B-III, C-II, D-IV
• C. A-III, B-IV, C-I, D-II
• D. A-III, B-IV, C-II, D-I

Hint:

Associate methods with materials: C-14 for anything once living (organic). K-Ar for volcanic rock. Thermoluminescence for things that were fired (pottery, burnt flint). Oxygen Isotope for climate data from deep sea or ice cores.

Answer 1

The Correct Option is C

Step 1: Concept Overview:
The task involves matching archaeological and geological dating (or paleo-environmental) methods with the materials they analyze.
Step 2: Detailed Analysis:
- A. Oxygen 16/18 Technique: This paleo-climatological method analyzes the ratio of oxygen isotopes ($^{18}$O/$^{16}$O) in foraminifera shells from deep-sea cores to reconstruct past temperatures and ice volume. Therefore, A matches with III.
- B. Radiocarbon (C-14) Dating: This method dates organic materials by measuring the decay of carbon-14. Charcoal, wood, bone, and shell are suitable for C-14 dating. Thus, B matches with IV.
- C. Potassium-Argon Method: This radiometric technique dates volcanic rocks by measuring the decay of potassium-40 to argon-40. Lavas and tuffs can be dated to determine the geological strata's age. Hence, C matches with I.
- D. Thermoluminescence (TL) Method: This method dates fired crystalline materials, primarily ceramics. Heating releases trapped electrons, and the emitted light measures the time since firing. Pottery is a typical sample for TL dating. Consequently, D matches with II.
Step 3: Solution:
The correct matches are: A-III, B-IV, C-I, D-II, which corresponds to option (C).
