Conservator: Paper treated with an alkaline deacidification process retains far more tensile strength after accelerated aging than otherwise similar untreated paper. The process is intended to slow deterioration by neutralizing acids already in the fibers and leaving an alkaline reserve that neutralizes acids formed later. Thus the treated paper's greater durability is probably produced by that acid-neutralizing mechanism.

Which one of the following, if true, most strengthens the argument?

  1. Several untreated papers manufactured recently are stronger than some treated papers manufactured a century ago, even after the tensile measurements are adjusted for sheet thickness.
  2. Blocking formation of the alkaline reserve lets treatment neutralize existing acid but removes most later durability gains.
  3. Treated sheets weigh slightly more than otherwise similar untreated sheets immediately after processing.
  4. Libraries using the process generally treat valuable documents before less valuable ones.
  5. The treatment slightly changes the color of some papers even when no accelerated aging follows.
