(1) AA. The opening line of the passage tells us that the astronomers were skeptical about astroid satellite systems ( "until recently many...."). In the 2nd para, the existence of such system became "respectable" (post Herculina). This marks a change in attitude. However, astronomers are not completely convinced. They are willing to change their minds if more proof is available. B. The astronomers show no dislike for theoreticians or with the position held by theoreticians. In fact, astronomical observations are cross checked with theoretical values to provide more verifiable conclusion.
C. The astronomers are not bemused at the chaotic mix of theory. What was stated by the theory is in fact observed the the astronomers & the collective output of both parties have led to a change in the astronomer's attitude. However, some of them call for more scientific data.
D. As stated in (A), skepticism transitioned into open mindedness. Therefore, choice D is wrong.
E. As stated in the last para, the astronomers call for verifiable scientific data to consider the hypothesis as true. Incontrovertible proof is yet to be established.
(2) CA. Theories were eventually backed by observations as true. Secondary occultations gave support to the hypothesis developed by theoreticians.
B. Nothing has been mentioned to link secondary occultations to collisions.
C
. Para e begins, "Observations NOW suggest....exist not only in theory....also reality" meaning prior observations of such occultations were less likely to have been reported. D. Prior to Heruclian, "well-behaved" secondary event standards did not exist, therefore there were no "prevailing standards"
E. Astronomers observed secondary occultations..this changed their views on asteroid-satellite system..Were they eager to publish it? We cannot infer.
(3) DA. % Increased 10X compared to the time prior to Herculina. Not implied. Especially since we have not been given any no. of Sec.Occ. prior to Herculina or post.
B. The only time 1/1000 case is mentioned is in para 2...to existence of asteroid satellite system if it resembles those of the planets.
C. As stated in (A), we do have have any "10X" or "absolute" number
D. Para 2 clearly states ...1/100 asteroid would be accompanied by a secondary event. E. "more than one secondary occultaion'? No such thing has been mentioned. Para2
(4) CA. Firstly, reports of secondary occultations are recent findings not existent. Secondly, such findings have not be subjected to doubt but accepted with some reservations
B. Separate theoretical hypothesis to spurious ones? Experimental efforts? Astronomers simply found new revelations that gave some traction to the hypothesis
C. The concept of asteroid-satellite system has seen incremental gains. The author reviews these development. D. The passage weighs in the astronomers' views on the topic...and introduces the theoretical view..The discussion on the topic has never been incomplete but rather different due to the lack of verifiable data. Subsequent lines show that with the findings of such data..the discussion leads to a more substantial , if not conclusive, end.
E. In the 3rd para, astronomers seek data from experimental observation to consider the hypothesis as true. But this alone is not the primary purpose of the passage.
