<EXAMPLE 1>
<Question>
Suppose we flip four coins simultaneously: a penny, a nickel, a dime, and a quarter.  What is the probability that at least 15 cents worth of coins come up heads?
</Question>
<Options>
COT (Chain of Thought, Language Only) – Solve the problem by reasoning through each step in natural language, breaking it down logically.
PAL (Program-Aided Language, Coding Only) – Directly write a Python program to solve the problem.
CodeNL (Coding First, Language Second) – First write a Python program, then reason and derive the final result.
NLCode (Natural Language First, Coding Second) – First provide a step-by-step reasoning process, then generate a Python program.
</Options>
<Reasoning>
Below is a brief assessment of each proposed method with respect to solving this specific question (calculating the probability that at least 15 cents come up heads when flipping four distinct coins):
## Which Method is Most Effective Here?
For this particular question—a small combinatorial probability problem involving just four coins—COT (Chain of Thought, Language Only) is often the most efficient and sufficiently reliable. Enumerating or systematically analyzing the 16 total outcomes can be done quickly and with minimal risk of error. While coding can confirm the answer, the problem’s small scale makes a purely logical enumeration both straightforward and transparent.

<Answer>
Selected method: COT.

Below is a brief analysis of each proposed method, focusing on how it applies to this specific geometry/algebra problem:
### Which method is most effective here?
Because this is a single, concise geometry question—finding a point on the \( x \)-axis that is equidistant from two points—a straightforward algebraic or geometric approach is typically quick and clear. A step-by-step, purely language-based explanation (COT) is perfectly sufficient and easily handled without requiring the support of code. Thus, for this specific problem, COT (Chain of Thought, Language Only) is the most effective method.
