While it does seem hard I do think Trinhcent has a valid point. We can't do anything to change the outcome now so there it is quite pointless to keep discussing some of the answers. Have to admit we are simply doing it at this point to feel better about ourselves.

~45 days couldn't come soon enough amiright

 

[Trinhcent]

Lol easier said than done

ahahaha I feel you

Its nice tho, having a place to discuss everything Fully understand the sentiment

Hey did anyone get a question yesterday?

 

[lillysayse]

Kinda glad I'm not the only one who wasnt certain about that snow one. Felt a bit silly not getting my head around it at the time. I thought it was saying the air bubbles are younger... Snow has to be there first before the air bubbles can form, so they're younger. Is my reasoning way off lol

It was kinda confusing, I guess only time will tell :sad:

from what i gathered from the stem, the snow had to reach a certain depth before air bubble formation was possible. Thus, the air bubbles were always formed after the snow and were therefore younger.

Yeah a couple

I thought that, as previously mentioned above, that the snow essentially was compressed into ice and thus was not classified as snow that point onward. I also know from arctic documentaries that used to watch a while back that snow does indeed compress into ice.

I don't remember if that was included in the stimulus and we should avoid bringing in outside knowledge. If it was in the stimulus, we weren't given information regarding how it affected the age of air bubble formation either. But we can't really change anything at the end hahahah.

See I totally had this reasoning too, EXCEPT, the snow that that had to fall before air bubbles could be created would have to turn into ice sheets from compact snow in order to create these air bubbles, therefore, the surrounding ‘snow’ (which hasn’t been turned into ice sheets yet) is actually younger than the air bubbles.

This is of course assuming that compact snow had to turn into ice sheets to create air bubbles in the first place.

Yeah tbh I thought it was an easy question and I was just dumb at the time but relieving to hear that many people found it not so easy

I believe it was mentioned in the stimulus which is why I picked 5250 but WHO KNOWS, we never will.

I have seen two dozen posts about this question but can't form an accurate picture of it. Were there multiple questions off one passage (since some talk about the bubbles' age in number of years some talk about younger/older than the surrounding snow)?

If the question was only about age in years than relativeness to original or surrounding snow is irrelevant. And since it's the age of the air bubbles it counts from when the bubbles FORMED; age of the air in it is irrelevant.

Hey A1, it was multiple questions from a stem, first one they gave you the rate of snow formation as being 20cm per year and that the snow had to be at least 50m for air bubbles to form (something very close to that). If the snow started falling 5000 years ago, how old were the air bubbles formed?
a) 5250 years ago
b) 4750 years ago
c) 5000 years ago
d) something else I cant remember

A second question compared two different areas, one with heavy or light snowfall. The question asked in relation to the surrounding snow how old would the air bubbles be?
A) same age, no difference
b) same difference from the surrounding snow in their respective areas
C) closer to snow age in high snowfall, whilst further from snow age in low snowfall
d) same as C but reversed.

I think those were the two stems associated with that question hahahah

The fourth option was 4500

Alright so I know this isnt the right way to look at it, but the answers were something like
a)5000
b)5250
c)4750
d)something also under 5000 (4850 maybe?)

ACER prefers to see your logical reasoning skills, not your maths skills. so i chose 5250, since its the only one higher than 5000. I reckon ACER didn't expect us to calculate the exact amount of years (although it was an easy calculation for most), but rather just whether he age was above, equal to, or below 5000 y/o.

I did consider putting down 4750, but i was torn, and the above reasoning is the reason i chose 5250. end of the day i guess it was a semi stab in the dark

hahahah all good, I've stated why I think its 4750 before so I'll just leave it at that let's just enjoy ourselves

There are countless Acer questions involving math skills?

yeah, the reasoning isnt exactly bullet proof haha but it was the only thing that made me put 5250 rather than 4750.
