At Flordyce University any student who wants to participate in a certain archaeological dig is eligible to do so but only if the student has taken at least one archaeology course and has shown an interest in the field. Many students who have shown an interest in archaeology never take even one archaeology course. Therefore, many students who want to participate in the dig will be ineligible to do so.
The flawed reasoning of which one of the following arguments is most similar to that of the argument above?
(A) Theoretically, any jar is worth saving regardless of its size, but only if it has a lid. Therefore, since some jars are sure not to have lids, there are certain sizes of jar that are actually not worth saving.
(B) For a horse that is well schooled to be ideal for beginning riders that horse must also be surefooted and gentle. Many horses that are surefooted are not gentle. Therefore many well-schooled horses are not ideal for beginning riders.
(C) If an author’s first novel has a romantic setting and a suspenseful plot, it will become a best-seller. Since many authors’ first novels have neither, not many first novels become best-sellers.
(D) Any automobile that is more than a few years old is eventually sure to need repairs if it is not regularly maintained. Many automobiles are more than a few years old, but still do not need repairs. Therefore, many automobiles are regularly maintained.
(E) An expensive new building will prove to be a good investment only if it is aesthetically pleasing or provides lots of office space. However, since many expensive new buildings are not aesthetically pleasing, few expensive new buildings will prove to be good investments.

Got B.
E says aesthetically pleasing OR provides lots of office space(either one), while the argument specifies one archaeology course AND interest in the field (both)
B looks perfect in that context

Please help me know how to choose between B and E. I fell for E.

B it is.
The arguments:
- To participate in the dig - Student must have: one archeology course + interest in the field.
- Many students have interest but no archeology course
=> Many students who want to participate in the dig will not be able to.
The flaw: "Many students" is not the same as "Many students who want to participate in the dig", for example, many students in the world has an IQ of 110, therefore many students in Harvard will have an IQ of 110.
B repeat the same flaws: "For a horse that is well schooled" is not the same as "Many horse", and plus B parallels in the reasoning with the original argument
E is not parrallel in the reasoning just as Ramana said, we need an "and", not an "or".
