A.I. Explanation:

Option 1: "It helps the baker make soft, spongy bread."

Explanation: While the text mentions bakers experimenting with soft, spongy bread, this example is not directly related to biotechnology being a solution to all problems of life. It illustrates early experimentation but does not encompass the broader implications of biotechnology.

Option 2: "Animal breeders can cross-breed to get favorable traits in the offspring."

Explanation: This statement reflects a historical practice mentioned in the text, but it does not address how biotechnology serves as a solution to all problems. It is a specific example of animal breeding rather than a comprehensive view of biotechnology's potential.

Option 3: "Biotechnology can help increase production, nutrition and add other characteristics."

Explanation: This option aligns with the main idea of the text, which states that biotechnology has led to advancements that help farmers increase production and improve nutrition. It captures the essence of biotechnology's role in addressing broader agricultural challenges, thus supporting the notion that it is a probable solution to life’s problems.

Option 4: "Biotechnology can help farmers to get pest resistant crops."

Explanation: Although the text mentions pest-resistant crops as a benefit of biotechnology, this option is too narrow. It focuses solely on one aspect of biotechnology's benefits rather than encompassing its overall potential as a solution to all problems of life.
