The Answer is D; Why is A Incorrect?

D is a more specific answer than A. "Available for" has less information in this context.

So many of these examples are not WRONG, in that people wouldn't know exactly what you meant, but they are imprecise or sound awkward natively. In this case, conducive means "doesn't promote". "Available to" isn't correct, and is a better term for when something is already occupied by something else or has gone away.

You're asked to choose the most precise word. "Available" might work, but it's very awkward. If something is "conducive" to a behavior, it is helpful to or encourages that behavior. The described process stops bacterial growth; it no longer is helpful to bacterial growth. Therefore, "conducive" is the best fit.

Available means that something is open and currently not being used, typically in a scheduling context. "The doctor is available to see you on March 4th." It's incorrect to say that an environment is available for bacterial growth, because bacterial growth isn't dependent on other things not using that space.

"No longer available for bacterial growth" doesn't really make sense. If something is *available*, it means you have access to it.

That's a tough one. Technically is available but that's not conveying the message. The sentence is saying bacteria can't grow there any more. So it's no longer conducive to growth. Schools are conducive for learning. They're available for winter Olympics but not conducive to the downhill slolam

Dang, that's an English language test? That's a rough test. D is the best answer. Just as adding two dozen Spongebob Squarepants impersonators makes a restaurant no longer conducive to romance, passing oxygen through a fluid makes that fluid not conducive to fermentation. A is the second best answer, but it's not quite right. A restaurant full of Spongebob Squarepants impersonators may be available for romance, but I wouldn't want to try.

The clue is in the wording of the question. It asks you to select the most logical and precise word to fit into that particular paragraph. If you read the paragraph carefully it is explaining that the experiment involves making fluid available to bacteria but passing oxygen through it so they can't grow and reproduce. So the fluid is definitely still available to the bacteria, it just isn't going to allow them to grow there because of the oxygen passing through it. So 'A' is incorrect.

"Available" is about access. Bacteria still have access to this environment, it's just not nice for them.

no longer conductive to: the conditions of bacteria growth are diminished no longer available to: no bacteria can grow there anymore by a lack of access It's about the change of conditions that lead to growth. 'Available to' would only be proper if some place got sealed off or something akin to that

as that old meme goes, "Don't try to Understand it... Feel it"

The environment is still available, it’s just that bacteria can’t survive there. I’m sure people would understand if you said A, but it’s asking for the most precise word, which is D.

I'd mostly want to know your thinking in answering with "available for." Because it's "available" regardless, but far from ideal here.

D: not conducive to

Passing oxygen through a liquid doesn't make in "unavailable." It's still there, and can still be used; it just won't work.

"conducive to" means it's suitable for or enabling a thing - it's about conditions. "Available for" technically means accessible in this context - it's about access and permissions. Bacteria aren't prevented from being in the fluid, but if they are in the fluid, they cannot ferment it because the fluid does not offer suitable conditions for bacteria growth.

It’s not nonsense, but 1), conducive more clearly relates to the promotion of certain processes; and 2), you can imagine certain ways in which available for, referring to environments and inanimate objects, is actually still the case in an objective way. So, in all, available seems to me less precise than conducive. However, I would not blink if one said *not available to* with “bacterial growth” in place of *not available for*, as it more clearly relates to the verb avail and hence processes. That the environment does not avail (itself to) bacteria growth may not be absolutely true, though; conducive is a less absolute choice. This reasoning may be a bit arcane, though, but it rings fine immediately in my ear. It’s not nonsense in any case!

Wow this is the first time in a long time that a test(?) had a question I understood. A lot of them seem to be based on regional English or by people who make bad tests. Anyways, yeah the other answers are correct. Conducive means something along the lines of "likely that a certain outcome will happen" or something. Ex: the noise was hardly conducive to sustained concentration

Scientifically, D isn't correct either. It's closer to C, but still not right. Firstly, the Pasteur effect was observed on *yeast* fermentation which is a fungus not a bacterium. Secondly, this kind of fermentation is a survival tactic for maintaining life in an anaerobic/anoxic environment. While yeast can 'grow' (i.e. divide) in a state of active fermentation, aerobic respiration is more efficient and conducive to cell growth, due to a greater efficiency in the metabolism of glucose. The only way I can make sense of the provided paragraph is if the author intends to suggest that fermentation is the growth of bacteria, which it most definitely is NOT.
