Explanation

The correct match is nominal with ethnicity, ordinal with satisfaction level, interval with year of death, and ratio with weight.

Ethnicity is nominal, an unordered classification.

Satisfaction level is ordinal, ranked from low to high without equal gaps.

Year of death is interval, with equal units but no absolute zero.

Weight is a ratio variable with a true zero, permitting ratios.

Calendar years lack a true zero, so a year cannot be twice another year.
