Two teams investigated whether a coating could slow the decay of wooden beams. The first collected information about the wood's age and moisture before beginning the treatment. The second used untreated beams as a comparison group and documented the amount of damage after six months. Their research produced several pieces of evidence supporting further trials, not a final recommendation for bridges exposed to salt water. Neither team had tested that environment. A funding panel welcomed the findings but asked the researchers to specify which claims were directly supported and which depended on an untested extension from the conditions already examined.

The report contains ①several pieces of evidence concerning the coating, but ②the information obtained from the short trial is limited. ③Much research remains necessary before engineers can recommend its use on older bridges. The committee requested ④an additional piece of advice from a specialist in salt-water corrosion. The specialist said that ⑤each of the findings support a more narrowly defined claim than the publicity material suggested. Her concern was not the number of observations alone, but the relationship between their conditions and the proposed application.

Before approving a coastal trial, the panel asked for (A) ______ about the range of salt concentrations used in the laboratory. It also wanted to know whether (B) ______ had been checked against the original measurements. The researchers replied that the observations covered only two concentrations and proposed a wider trial rather than presenting the present results as sufficient for every coastline.
