ditransitive vs monotransitive

[sabiha]

Hi,
I have met the following difficulties while analysing my corpus.
I have classified the following verb as ditransitive. Do you agree with me?
- Incremental benefits of quadrivalent vaccination do not have a large effect on the cost differential.

I have classified the following verbs as monotransitive. Do you agree with me?
- Costs were discounted at 3.5% per year.
-The annual number of unique warts episodes was estimated at about 156 000.



Best regards

You seem not really to understand the terms in question.

A ditransitive verb is one such as 'give' or 'tell' which can govern both a direct and a (non-prepositional) indirect object. Neither of the examples you cite would fall into that category.
