Step 1: The passage uses the phrase \textit{"When I was a kid"}, indicating that the narrator is now reflecting back on childhood. This shows it is written from an adult’s perspective.
Step 2: The narrator recalls being partial to stories about other worlds and interplanetary travel. This is clearly a memory of past preferences.
Step 3: Option (A) is incorrect because it is not a child describing in the present but an adult reminiscing. Option (C) is not supported because there is no mention of “only in parts.” Option (D) makes a general claim beyond the passage.
Step 4: Hence, the correct inference is that it is an adult’s memory of what he or she liked as a child.
