LSAT Question Complete Explanation

First, let's understand the passage. It states that creativity is based on the ability to create variations on a theme. In the history of science, every idea is built on a thousand related ideas, and what we call a new theme or discovery is always a variation of previous themes on a deep level.

The question type is Must Be True EXCEPT, meaning we need to find the answer choice that does not necessarily follow from the passage.

Now let's analyze the answer choices:

a) A lack of ability to manufacture a variation on a previous theme connotes a lack of creativity.

This choice follows from the passage, as it states that creativity resides in the ability to create variations on a theme. If someone lacks this ability, they lack creativity. This answer choice is not correct.

b) No scientific idea is entirely independent of all other ideas.

This choice also follows from the passage, as it mentions that every idea is built on a thousand related ideas. Therefore, no idea is completely independent. This answer choice is not correct.

c) Careful analysis of a specific variation can reveal previous themes of which it is a variation.

This choice is supported by the passage, which states that careful analysis helps us understand that new themes or discoveries are variations of previous themes. This answer choice is not correct.

d) All great scientific discoverers have been able to manufacture a variation on a theme.

This choice logically follows the passage, as it states that new discoveries are always variations on previous themes. Therefore, great discoverers must have been able to create such variations. This answer choice is not correct.

e) Some new scientific discoveries do not represent, on a deep level, a variation on previous themes.

This is the correct answer choice. The passage states that every new theme or discovery is always a variation of previous themes. This answer choice contradicts the passage, suggesting that some discoveries are not variations on previous themes. Since this statement does not necessarily follow from the passage, it is the correct answer.
