[All LSAT Section 1 Logical Reasoning Questions]

Theoretically, analog systems are superior to digital systems. A signal in a pure analog system can be infinitely detailed, while digital systems cannot produce signals that are more precise than their digital units. With this theoretical advantage there is a practical disadvantage, however. Since there is no limit on the potential detail of the signal, the duplication of an analog representation allows tiny variations from the original, which are errors. These errors tend to accumulate as signals are duplicated, until this "noise" obliterates the information embodied in the original signal.
The statements above, if true, most strongly support which one of the following?

A. Many ideas that work well in theory do not work well in practice.
B. Analog representation of information is impractical because we do not need infinitely detailed information.
C. Digital systems are the best information systems because error cannot occur in the emission of digital signals,
D. Analog systems are inferior to digital systems for most practical purposes.
E. Digital systems are preferable to analog systems when the signal must be reproduced many times.

Suggested Answer: E 🗳️
We see an Inference stem and a lot of text, so we should gear our attack on the stimulus accordingly, scoping out the more concrete facts and looking to interpret and combine as we go. In theory, were told, analog systems trump digitalones, and sentence 2 tells us one way thats soa difference in the detail and precision of their respective signals. But theres a very real downside to this theoretical advantage: The detail possible in an analog signal allow for errors to creep in during duplication, and the resultant noise can eventually drown out the original signal. Theres nothing really obvious in the way of connections here, so well have to rely on a careful evaluation of the choices.
