Most scientists agree that saturated fats contribute to high levels of "bad" cholesterol in a person's blood, while monounsaturated fats and polyunsaturated fats lower this type of cholesterol in a person's blood. The table below shows data about fats in some common foods.

\begin{tabular}{|l|l|l|l|}
\hline
Food (14 g) & Saturated fat (g) & Monounsaturated fat (g) & Polyunsaturated fat (g) \\
\hline
Canola oil & 1.0 & 8.9 & 3.9 \\
\hline
Margarine & 1.6 & 5.4 & 3.4 \\
\hline
Olive oil & 1.9 & 9.9 & 1.4 \\
\hline
Lard & 5.0 & 5.8 & 1.4 \\
\hline
Butter & 7.9 & 3.7 & 0.5 \\
\hline
\end{tabular}

Joyce and Linda are identical twins who are 50 years old and enjoy exercising daily. Joyce avoids eating any dairy or animal products and eats granola made with canola oil for breakfast. Linda prefers rich foods and eats bacon, eggs, and buttered toast each morning.

Which statement describes a logical inference that can be made from the provided information?

A. Butter has higher levels of saturated fats in it than canola oil.
B. Linda and Joyce both have high levels of "bad" cholesterol.


Sagot :

Let's start by looking closely at the data presented in the table regarding the fat content in various foods:

1. Canola oil:
- Saturated fat: 1.0 g
- Monounsaturated fat: 8.9 g
- Polyunsaturated fat: 3.9 g

2. Butter:
- Saturated fat: 7.9 g
- Monounsaturated fat: 3.7 g
- Polyunsaturated fat: 0.5 g

We need to compare the levels of saturated fats in canola oil and butter. The key focus here is on the saturated fat content.

### Step-by-Step Analysis:
1. Reading the Saturated Fat Content:
- Canola oil contains 1.0 grams of saturated fat per 14 grams of the food.
- Butter contains 7.9 grams of saturated fat per 14 grams of the food.

2. Comparing Saturated Fat:
- We see that 7.9 grams (butter) is greater than 1.0 grams (canola oil).

Since butter has a higher saturated fat content (7.9 grams) compared to canola oil (1.0 gram), we can make a logical inference about the saturated fat content.

### Inference:
The statement "Butter has higher levels of saturated fats in it than canola oil." is logically correct based on the data provided.

As for the second statement "Linda and Joyce both have high levels of 'bad' cholesterol.", we don't have direct measurements of their cholesterol levels, only information about their diets. Thus, we cannot conclusively infer this from the data alone.

Therefore, the valid logical inference that can be made from the provided information is:
Butter has higher levels of saturated fats in it than canola oil.
