Question

read the sentence from the video transcript of dr. x and the quest for food safety.

we have one of the safest food supplies in the world, but theres always room for improvement.

which sentence from the video provides the best support for this statement?

there are a lot of ways bad bacteria can find their way into our food.
theres a whole underworld of bacteria out there that we must monitor.
this little bacterium has all of the genetic information to make copies of itself.
under the right conditions, a single bacterium will double with each division.

Explanation:

Analyze the target statement

The target statement is: "We have one of the safest food supplies in the world, but there's always room for improvement." This statement contains two key ideas:

1. The food supply is generally very safe.
2. There is still room for improvement (implying potential risks, hazards, or areas that require ongoing vigilance/monitoring to maintain or improve safety).

Evaluate the options

• Option 1: "There are a lot of ways bad bacteria can find their way into our food."
• This directly supports the second part of the statement ("there's always room for improvement") by explaining why improvement and vigilance are constantly needed—because there are numerous pathways for contamination.
• Option 2: "There's a whole underworld of bacteria out there that we must monitor."
• While monitoring is important, this is a general statement about the existence of bacteria rather than a direct explanation of the vulnerability or need for improvement in our food supply chain.
• Option 3: "This little bacterium has all of the genetic information to make copies of itself."
• This is a purely biological fact about bacterial reproduction and does not directly support the claim about food supply safety or the need for systemic improvement.
• Option 4: "Under the right conditions, a single bacterium will double with each division."
• This is another biological fact about bacterial growth rates and does not directly address the safety of the food supply or the pathways of contamination that necessitate improvement.

Determine the best support

Option 1 provides the most direct, logical support for why a safe food supply still has "room for improvement" by highlighting the multiple vulnerabilities (the many ways bad bacteria can enter).

Answer:

• (A) There are a lot of ways bad bacteria can find their way into our food. (Correct answer)
• (B) There's a whole underworld of bacteria out there that we must monitor.
• (C) This little bacterium has all of the genetic information to make copies of itself.
• (D) Under the right conditions, a single bacterium will double with each division.
