Grammar Editing Question

\"Thrice a week, Mr Wan Chong Hock inspects the HDB blocks in Ang Mo Kio and neighbouring Yio Chu Kang constituency. His town council is (1) within 16 others across Singapore that (2) is being assessed for the first time on their performance..........\"

anwer keys :
(1) among
I feel that among is not a good choice because of the '16 others'. My best answer is 'with'. What's your opinion ?

(2) are

The answer \"among\" is correct. There are several ways to use this preposition. In this case, \"among 16 others\" means \"in association with 16 others\".

To use \"with\" in this sentence is incorrect, unless the sentence was \"His town council, together with 16 others across Singapore, are being assessed...\"

Hi Mdm,

I believe you have inadvertently typed 'are' instead of the correct 'is'.

His town council, together with 16 others across Singapore, is being assessed.

Daddy:

hi all,


Need help on this question. Thanks

A skirt cost 1/3 as much as the cost of each pair of shoes. If Tricia bought 2 skirts and 5 pair of shoes for $799, how much did she pay for each skirt?

Thanks

1 Sk --> 1 u
2 Sk --> 2 x 1 = 2 u

1 Sh --> 3 u
5 Sh --> 5 x 3 = 15 u

17 u --> 799

1 u --> 1/17 x 799 = $47

It was $47.

Hi,

I think the correct answer is \"water\" because when carbon dioxide is used up, the plant can replenish it through respiration and photosynthesis can continue until the water in the beaker is depleted.

I will agree that the answer is \"water\" if the question is, \"what caused the photosynthesis to finally STOP?\" However, the quesion says the rate of photosynthesis is decreasing.....and is due to what? Since the DECREASE in the rate of photosynthesis is initiated by the lack of CO2, the answer will be CO2. (Plant stores CO2, a process known - carbon sequestration. Therefore, the amount of CO2 released will be less and less. Finally, there is no more CO2 and part of plant will die, leading to decomposition and CO2 is released and the cycle continues)

yes, i remember this question - my ds put CO2 as the answer as he also said the same as what atutor said above. I checked with my ds - indeed the question did ask why the rate of photosynthesis is decreasing not stop. wow these days psle question so tricky....[/quote]
I also hope that the answer is CO2, otherwise my sister will lose 2 marks.

During her revision, she was asking me about what are the factors that can be changed to get the same experimental results.
My answer was intensity of light, temperature of water, the number of hydrilla, the type of water plant or amount of CO2 (one of these is already the changed factor for the experiment), but never to put amount of water as the answer because it was a fully submerged plant and the amount of water was not going to factor the results.
So for this question, she just ruled out water, ignoring that the plant is a land plant.

sorry, atutor, the description is not that accurate. it's actually in the psle science paper this year. According to my daughter, the plant is in a sealed beaker of water (no soil) but only the root part is immersed in the sealed beaker. and it's placed under the lamp, not the sun. The rest of the details are correct. Sorry for the confusion. I should have clarified with her first before putting the question down on this forum.


Anyway, just to comment - lots of dd's classmates put CO2 being the answer but others put water.

Hi,

My answer is carbon dioxide as the plant is in a container with limited air. Air only contains 0.03% carbon dioxide. Most of my classmates also choose carbon dioxide as their answer.

You are right, they don't put that in Science. Does that mean drawn to scale? Haha, what can I say then? It makes me think of nowadays a lot of ads also quote \"picture shown only for reference. Actual item may differ from picture shown\"...so what is shown may or may not be what is shown, it's difficult to assume.


BTW Tianzhu, the Science teacher had informed the boy in my daughter's class about the 2 balls collision answer just before they sat for the PSLE Science exam yesterday. Now the teacher said the answer is (1) after confirmation with the Science HOD without explanation. Answer (1) is;

I've read the link you've given last Sunday, thanks. I played snooker but to achieve elastic collision needs certain level of skill.

[quote=\"chrisu\"]As it's Science question, unless the question specified that the diagram shown is actual size, I think it's unfair to expect the students to draw lines to see the shadow cast. If the diagram shown is actual size or in good ratio proportion, then drawing straight lines from the light source is a good way to see the shadow cast. Otherwise we can only guess the actual distance between objects and light source.

Maybe you have not noticed. In math geometry question, all questions will have the print \"Not draw to scale\". However, we seldom see such wordings in Science questions. Hope you understand what I mean.

Hi,

My answer is (1) as some energy has been converted to sound energy and heat energy.

Hi,


My sister’s answer is "circle" and I hope that she is correct.

Hi All,


For the question below (for question part a), the answer key is \"Oxygen\". Can some body please explain this?

My DS answer is Carbon dioxide.

Thanks in advance..

Hi,

The answer is given in part b - oxygen.
The aim also mentions photosynthesis, so output is oxygen.
