One should not increase, beyond what is necessary,
the number of entities required to explain anything.

Understanding of word arithmetic problems with extraneous information was chosen for computer simulation because only basic skills are needed for such understanding. In order to determine whether the computer understands those problems, it must solve them. The solution correctness serves the estimation of the understanding.
The goal was achieved; the routine ROBUST successfully solves entangled text problems and detects redundant information. This lets to observe all actions which are needed to understand the problem text.
I developed a method for erroneous data detection. The method was implemented in a computer program Consensus5. This routine can be applied in the variety of fields, e.g. for processing of experimental data in physics, chemistry, and biology; for the treatment of expert estimations, for detection of defective devices and so on. The method also provides felicitous graphical presentation. The linked paper contains examples of applications.
I developed a clear physical interpretation for the basic evidences of general relativity. Instead of curved space it is suggested to consider structural properties of a particle and with their help to explain the behavior of the latter. The basic evidences of general relativity can be derived by means of simple models conceivable for undergraduate students.
