What Constitutes a Real Aptitude Test?

In a previous blog, see http://brane-space.blogspot.com/2013/08/why-so-many-past-aptitude-tests-are-no.html

I noted why most current standardized exams, including the SAT, GRE and others, no longer qualify as bona fide aptitude tests and hence can no longer be used for entry into the high IQ societies, such as Mensa, Intertel. This elicits the question of what a real aptitude test would look like, what type of questions would be seen?

As an example, I can present some sample questions from the (1985) Graduate Record Exam I took (test booklets could be purchased with score release), which result (1330 verbal + quant.) qualified me not only for Mensa entry but Intertel as well  - and also a $9800/yr  post-graduate research assistantship at the University of Alaska-Fairbanks. The test was grueling to say the least, lasting a full 210 mins. (3 1/2 hours) with 30 questions each in 7 sections (30 mins. allowed per section) alternating verbal, quantitative and analytical questions. The questions also varied in complexity. In the case of the verbal portions they ranged from simple recognition of opposites and analogies, etc. to parsing complex paragraphs from diverse writings then interpreting them. In the case of the quantitative sets, they varied from simple algebraic, arithmetic,  geometric or trig questions to analyzing graphs then addressing aspects of them via the questions. The point to bear in mind is that no matter how "simple" the questions may appear, they're not based on rote memory or content but on aptitude.

Since basically there  is only one minute per question on average, then if anyone attempts this as a sample test, you have no more than 20 minutes to complete it.  In the interest of space conservation I have focused only on the shorter version of questions - no lengthy ones. Thus finishing in the time  may be somewhat misleading - since obviously more complex questions (which are excluded) would consume more time.

With those provisos, here goes:
