Answer:
-a magazine article that uses other reliable sources
-a book written in 2014 by a high school teacher
-a recent online journal article by a professor of technology education
Explanation:
A reliable source should be credible, allow to identify the author who should have knowledge about the topic he/she is talking about, it shouldn't be old as it could be outdated and it shouldn't have grammar mistakes. According to this, the sources that would be reliable for a research paper about the use of technology in school are:
-a magazine article that uses other reliable sources
-a book written in 2014 by a high school teacher
-a recent online journal article by a professor of technology education
The other options are not right because a web page that has spelling and grammatical errors cannot be trusted, a journal entry written by a high school student could be subjective and the student is not an expert on the topic and a newspaper article written in 1985 is too old.
All these words would apply for a synonymy for abundant. Plentiful, copious, ample, profuse, rich, lavish, liberal, generous, bountiful, large, huge, great, bumper, overflowing, superabundant, infinite, inexhaustible, opulent, prolific.
Hope this helps
