The article talks about two companies that dig up copper from the ground. One is called Freeport-McMoRan and the other is Teck Resources. Copper is an important metal used in many things, like wires and electric cars. People who own parts of these companies can make money if the price of copper goes up or if the company grows. The article says that both companies could do well, but Teck Resources might be a better choice for people who want to make more money because it has lower prices and is growing faster.

1. The author does not provide any evidence or data to support their claims that Teck Resources has more upside than Freeport-McMoRan. They simply state their opinion without any factual basis. This is a logical fallacy known as an argument from authority, where the writer assumes their own judgment is valid merely because they have some expertise in the field.
2. The author also fails to acknowledge the risks and challenges associated with Teck Resources' growth initiatives, such as environmental regulations, market volatility, and competition from other copper producers. This creates an unbalanced view of the company's prospects and ignores potential downside scenarios.
3. The author uses emotional language to appeal to readers, such as "tilt the scales in its favor" and "preferred choice", which imply a clear bias towards Teck Resources without providing any objective analysis or comparison of the two stocks. This is an example of persuasive writing, where the writer tries to influence the reader's opinion by using emotional appeals rather than rational arguments.
4. The author does not address the impact of the COVID-19 pandemic on both companies and their respective copper production and demand outlooks. This is an important factor to consider when evaluating the future performance of any stock, especially in a volatile and uncertain market environment.

{main points}
- Teck Resources is the better choice for investors seeking greater upside potential and favorable valuation, driven by its diversified portfolio and growth initiatives.
- Freeport-McMoRan offers stability and incremental upside through its existing asset base and near-term growth opportunities, but has a higher price target and less relative upside compared to Teck Resources.
