`  == More about Barriers ==  The second paragraph presently begins: Study tech attempts to remove what it calls ``barriers to study``.  Study Tech defines 3 barriers.  As a dictionary defines words and as biology defines the cell ``nucleus`` and the ``cell membrane``, well, Study Tech defines 3 barriers which it says exist.  It says, ``there are three barriers to study``, that is its message.  It spells out the barriers and it says how to deal with these barriers when a student encounters them.  Could we have Study tech defines three barriers to study and purports a methodology of dealing with them? The reason the present sentence is not accurate is because no matter how many times a student removes a barrier, he may meet the same barrier in the next word he reads.  A student educates himself and then deals with barriers when he meets them.  `
