As far as I know, all the MT papers are pegged at the same standard. That's why picture for compo are all the same; same goes for oral. Maybe the compre passages are the same too, just translated into different languages.[/quote]r2010:
[quote=\"hashroop\"]I'm not surprise at no Malay, Tamil and NTIL postings here on this thread.
When the t score is calculated. Is the standard deviation and mean for malay Tamil Chinese and ntil is separately calculated?
Will the mean and standard deviation used for all the MT will be based on individual MT ie Malay, Tamil or Chinese or the overall mean and standard deviation for Malay, tamil and Chinese -
Ms tay:
Logically C is true cos shade definitely will block off sunlight and cool down the temperature.
A and b are definitely correct as all the options have a and b. C is wrong as c happens only because of the depletion of the ozone layer and global warming isn't involved. For d, the life forms also refer to plants as they have lives too, and when all of them die,decomposition happens and more carbon dioxide will be released into the atmosphere and would thus enhance global warming. So, my answer is (3) hope this helps....Verysuperkiasu:
Posted this on science thread but no answer. does anyone know the answer? desperate.....no one answered yet.
Question:
Cutting down of trees will cause the phenomenon 'global warming'. Which of the following are involved in global warming?
A: burning of trees causes the carbon in the tree to combine with oxygen in the air to form carbon dioxide.
B: Carbon dioxide in the atmosphere acts as a blanket to trap heat in the Earth.
Without trees, Sun heats up te Earth's surface directly.
Soil erosion will destroy aquatic life forms, which in turn will enhance global warming subsequently.
(1) A and B only
(2) A, B and C only
(3) A, B and D only
(4) A, B, C and D
Answer is (4). My son doesn't think C and D are involved in global warming. Is he correct or is he wrong. His answer is (1).
And that has nothing to do with the ozone layer which is another story.
Ozone layer problem mainly concerns UV light radiation and not global warming.
So I think it's 4. -

Mwahahaha XD:
Our sch top scorer cheated for paper 1 eh... Will minus 40 or 100 uh? Anyone noe?
She DID not cheat for paper 1. She got misunderstood. she wanted to change the answer but heard 'times up' so she flip back to cover page. just that some people think she's cheating. And she proved she did not cheat -

No point calculating marks because they are just raw score. What one should be concern is the final t score.Essential:
Just curious how u know the marks so far
My DD minused 8 marks for part 1 and as far as i noe, she got full marks for pp2 haizz -
Yes, my girl said it’s a manageable paper.

Should be. Cos their standard may be different.

Usaully the t-score for chinese is the lowest compared to the other three languages am I right ??
[/quote]
So, if the tamil is tougher than Mandarin for this year, so the mean will be lower and t score will be higher?[/quote]
Depends on its standard deviation as lesser people take Tamil. -

Global warming refers to an average increase in the Earth's temperature, which in turn causes changes in climate. A warmer Earth may lead to changes in rainfall patterns, a rise in sea level, and a wide range of impacts on plants, wildlife, and humans. When scientists talk about the issue of climate change, their concern is about global warming caused by human activities.
Hopes this help
