Question 21

An increase in protein affects energy levels.

The advertisement suggests that 76% of customers report having more energy after consuming Pro-10 shakes, which implies a correlation between increased protein intake and enhanced energy levels.

A) An increase in protein affects energy levels.

This option is correct because the advertisement explicitly states that a significant percentage of customers experienced increased energy after consuming Pro-10 shakes, which are high in protein. This supports the inference that an increase in protein can positively impact energy levels.

B) Seventy-six percent of customers felt better in 3 weeks.

This option is incorrect as the advertisement specifies that customers reported feeling more energy after drinking Pro-10 for just 2 weeks, not 3 weeks. Therefore, this statement misrepresents the timeframe mentioned in the ad.

C) Pro-10 shakes are affordable.

This option cannot be concluded from the advertisement. There is no information provided regarding the pricing or affordability of Pro-10 shakes, making it impossible to infer their cost-effectiveness based solely on the text.

D) Pro-10 shakes contribute to a person's overall health.

While the advertisement implies that the shakes can improve energy levels, it does not provide direct evidence that they contribute to overall health. Therefore, this option is not a reasonable inference based on the information given.

Conclusion

The inference that an increase in protein affects energy levels is supported by the data presented in the advertisement, specifically the 76% customer feedback. Other options either misinterpret the information, lack sufficient evidence, or introduce concepts not mentioned in the text, thus failing to align with the core message regarding energy enhancement through protein.
