Question

technician a says that the super - ultra - low emissions vehicle (sulev) has the most stringent emissions standard. technician b says that the most stringent emissions standard is largely restricted to electric and hydrogen - powered vehicles. who is correct? a. technician a b. technician b c. both technician a and technician b d. neither technician a nor technician b

Explanation:

SULEV (Super - Ultra - Low Emissions Vehicle) has very strict emissions standards, but the most stringent emissions standards are for Zero - Emission Vehicles (ZEVs). ZEVs are mainly electric and hydrogen - powered vehicles as they produce no tailpipe emissions. So Technician A is wrong (SULEV is not the most stringent) and Technician B is correct (most stringent is for electric and hydrogen - powered which are ZEVs).

Answer:

b. Technician B
