A journal article cited "122 Va L.Rev. 75" begins on what page number?

Give the legal citation to the May 15, 1972 U.S. Supreme Court ruling inWisconsin v. Yoderusing ONLY the "L.Ed.2d" Reporter. (Include volume, page number, and abbreviation of the reporter ONLY.)

What is the abbreviation used to refer to a law passed by the U.S. Congress?

NOTE: There is no additional information to provide. I imagine each answer can be found in the journal or case being reference in the question
