Statement–Assumption — “Traffic police will be provided with alcometers to identify drunken drivers.” — Police chief Assumptions: I) Many accidents occur due to drunken driving. II) An alcometer can easily identify persons under the influence of alcohol. Choose the implicit assumption(s).

Introduction / Context:
Issuing alcometers is a targeted enforcement response. For such a measure to be justified, both the problem (drunk driving harms) and the tool’s efficacy must be presumed.

Given Data / Assumptions:

• Drunk driving elevates crash risk.
• Alcometers measure breath alcohol reliably for screening.

Concept / Approach:
The policy presupposes that alcohol-impaired driving significantly contributes to accidents (problem significance) and that alcometers can detect impairment (tool effectiveness). Without either, the measure would lack rationale.

Step-by-Step Solution:

Verification / Alternative check:
Standard policing worldwide uses breathalysers for roadside screening, confirming II.

Why Other Options Are Wrong:
Choosing only one leaves the policy either purposeless or ineffective.

Common Pitfalls:
Confusing evidentiary confirmation tests with preliminary screening—both can be parts of protocol.

Final Answer:
Both I and II are implicit.
