Question

Match the acronyms in Group I with the particulars in Group II. 
\[\begin{array}{|c|c|} \hline \textbf{Group I} & \textbf{Group II} \\ \hline \text{P: LCA} & \text{1: building certification system} \\ \hline \text{Q: IPCC} & \text{2: hydrological assessment tool} \\ \hline \text{R: Mtoe} & \text{3: climate change} \\ \hline \text{S: LEED} & \text{4: equivalent measure of energy expended} \\ \hline & \text{5: cradle to grave} \\ \hline \end{array}\]

• A. P–3, Q–5, R–4, S–2
• B. P–4, Q–3, R–1, S–2
• C. P–5, Q–4, R–2, S–1
• D. P–5, Q–3, R–4, S–1

Hint:

When matching acronyms to their definitions, always focus on the primary purpose or application of each term to avoid confusion with similar-sounding terms.

Answer 1

The Correct Option is A

Step 1: Understand each acronym.
1. LCA (Life Cycle Assessment): LCA is a method used to evaluate the environmental impacts of a product or process throughout its entire lifecycle. This includes everything from raw material extraction to disposal (i.e., cradle to grave). Therefore, LCA corresponds to 5: cradle to grave.
2. IPCC (Intergovernmental Panel on Climate Change): The IPCC is an organization that assesses scientific information related to climate change. As its primary role is to study climate change, IPCC corresponds to 3: climate change.
3. Mtoe (Million Tonnes of Oil Equivalent): Mtoe is a unit of energy measurement, typically used to quantify large amounts of energy, especially in the context of fossil fuels. It represents an equivalent measure of energy expended, so Mtoe corresponds to 4: equivalent measure of energy expended.
4. LEED (Leadership in Energy and Environmental Design): LEED is a globally recognized certification system for the design, construction, and operation of high-performance green buildings. It is a building certification system, making LEED correspond to 1: building certification system.

Step 2: Final matching.
Based on the descriptions above, we match the items as follows:
- P (LCA) matches with 5: cradle to grave
- Q (IPCC) matches with 3: climate change
- R (Mtoe) matches with 4: equivalent measure of energy expended
- S (LEED) matches with 1: building certification system
Thus, the correct matching is: \[ P-5,\ Q-3,\ R-4,\ S-1 \] This corresponds to option (D).
