Question

Read the following statement carefully and identify the conclusion that follows. Statement: The bank has introduced a biometric login system.

1. The bank wants to improve security.
2. Customers must carry biometric IDs.

• A. Only Conclusion I follows
• B. Only Conclusion II follows
• C. Both I and II follow
• D. Neither I nor II follows

Answer 1

Answer:

A. Only Conclusion I follows

Analysis of Logical Inference

• Statement Logic: The introduction of a biometric login system by a bank is a strategic decision. In logical reasoning questions, one must deduce the most immediate and intended objective behind such an implementation.
• Evaluating Conclusion 1: The bank wants to improve security. This is a logical inference. Biometric systems (fingerprint, retina scanning, etc.) are universally implemented to reduce unauthorized access, prevent fraud, and verify user identity more reliably than traditional passwords or PINs. Therefore, enhancing security is the primary, direct objective of this change.
• Evaluating Conclusion 2: Customers must carry biometric IDs. This statement is an assumption that is not necessarily true. Biometric systems typically use physical attributes (like fingerprints) already present on the user's body, rather than requiring the user to carry an external identification document. The statement mentions 'login system' rather than an 'identification requirement,' making this conclusion invalid or extraneous.

Exam Strategy Tip:

• Focus on Intent: When analyzing 'Statement and Conclusion' questions, prioritize the underlying purpose or motive of the action described in the statement.
• Avoid Over-generalization: Eliminate conclusions that require assumptions not directly supported by the text (e.g., assuming a specific method of operation, such as carrying a card, when only the 'system' is mentioned).
• Standard Practice: Biometric authentication is a standard industry practice in banking to strengthen Know Your Customer (KYC) protocols and multi-factor authentication (MFA) frameworks.
