The report on the gross national product—the nation’s total production

In this case "second quarter inflation", a noun, is compared to "previously estimated", a verb.
Is this a correct comparison?

present inflation rate is compared to inflation rate previously estimated
no need to repeat as to keep sentence short and precise

"second quarter inflation is lower than inflation previously estimated.

hope this helps

The report on the gross national product—the nation’s total production of goods and services—showed that second-quarter inflation was somewhat lower than a previous estimation and the savings rate slightly higher.
(A) a previous estimation and the savings rate slightly higher (incorrect: comparison and parallelism error)
First, inflation was lower than estimation which is incorrect. Inflation cannot be estimation instead inflation can be estimated. Second, inflation was lower and the savings rate higher is incorrect. It should be was lower and was higher.
(B) a previous estimation and with a slightly higher savings rate (incorrect: comparison and parallelism error)
The same error as option A has. Moreover, with a slightly higher savings rate is not parallel with inflation was lower.
(C) a previous estimate and that the savings rate is slightly higher (Incorrect: comparison and tenses error)
Comparison error is the same as options A and B have. Additionally, the savings rate is should savings rate was as the first clause is in the past.
(D) previously estimated and a slightly higher savings rate (incorrect: parallelism error)
And a slightly higher savings rate is not parallel with inflation was higher.
(E) previously estimated and that the savings rate was slightly higher (the best option)
Following the comparison and parallelism structure and rule.
