1. OA: C
Tag: big picture
The passage discusses the different aspects of the clown fish behavior: relationship with sea anemone, mating behavior, maturation etc. Option C is therefore the most relevant.
A: Too broad; the passage is only concerned about the clown fish
B: Comparison of hermaphroditism - incorrect
D: Prospective research - incorrect
E: does not reconcile this - incorrect
Solution 2. OA: A
Tag: inference
The scope lies here : ”A special mucous coating that serves as a chemical camouflage allows clown fish to live among the deadly tentacles of the unsuspecting sea anemone.” This is given in line 2.
The word “camouflage” suggests that the sea anemone does not detect the presence of the clown fish.
B: insufficient evidence to support this.
C: insufficient evidence to support this.
D: In contrast they actually do come in close proximity with the anemone
E: This is commonsensical but is NOT supported by the information provided in the passage - eliminate
Solution 3. OA: C
Tag: inference
Sex change happens an adult female is removed. In the absence of the adult female, the adult male becomes female. This can be prevented if an adult female is available in the group. Therefore option C is true.
A: that the male needs to be larger is not substantiated by the passage
B: This does not point towards the reduced need for sex change
D: This would only have an adverse effect and will not help reduce rate of sex change
E: This again would do nothing to reduce the rate of sex change
Solution4. OA: E
Tag: Anchor Phrase
The passage provides proof for options A, B, C and D (2nd para). There is no substantiation for option E though. Option E therefore is the correct response.
A: …. A remarkable adaptation is that development of juveniles is somehow…. Suggesting that only one female is reproductively active at any given time. A is true
B: is dominated by a monogamous breeding pair…. B is true
C: …. A remarkable adaptation is that development of juveniles is somehow…. Shows how the community grows in synch in response to the hierarchy C is true
D: while the community thus economizes on limited space and food source… suggesting that there is a fixed upper cap to the population in the community D is true
E: There is no proof suggesting this and E is therefore the correct response
