To speed the process of surveying, surveyors use brass metal plates to record important information. The benchmarks, as they are called, are used to save time so surveyors do not have measure the datum plane each time. Benchmarks refer to what standard of measurement?

Construction surveys are those surveys that provide line and grade.

Explanation:

Benchmarks for surveying the construction site involves the fixed reference point along with a precisely published elevation levels. In the given condition, the brass metal plate is used to record and measure parameters from the set benchmark. This will save the time of the survey.

Due to direct relationship between asset and liability.

Explanation:

Yes, increase in one asset will cause a decrease in another asset and an  increase in one liability because of the direct relation between asset and liability and inverse relation between two asset. Direct relationship means if increase occurs in one thing or factor so the other factor also increases whereas if decrease occur in one thing or factor also decrease the other factor so if one asset is increases the liability is also increases.
