Just came back......
Somehow, my keybord can not input Chinese... In order to appreciate the help from CDers, and help more.....

I just type the JJ that I can remember as below......


AWA:

Both not now appear before, at least new to me.Below just my recalls, please refer the OG12 writing for original issue or argument.

AA: People should stick on their current job, key points are 1) self-employed working at home will have a lot of distractions and noise; 2) When people are self-employed, they are more isolated and less socialized then normal ones who work in office; 3) people will have a better career if sticking on same job for long time.

Note: easy to argue, and no numbers.

AI: People should not develop new technologies which cause a lot risk at nature environment.



Q:

1. DSQ: How tall(vertical) from the bottom of the ground to the top of the both flags?There is no other data provide in the statement except giving the height of the two flags.

1) give the slop & angle=60. ( OK)

2) the distance between the point at the corner of the slop at ground and the point at exactly below the flag at ground. (X)

60o

Challenge is to understand the question.

The answer format is 10⁵(10⁵-2)

3. DShow to get abx>aby?

1）ax>ay

2）bx>by



I choose E

4.Choice -ask the “y2” .

The condition is A(x0,y0), B(x1,y1), C(x2,y2) are three points in xy plane, and x0,y0,x1,y1,x2 are integers. AB is perpendicular BC.

The answer is “ E” :10

5. Six exactly same holes drilled in a round plate. the same as this one of JJ. The distance from one of the small holes are the same as others two besides(?).

1) the center from holes to the center of the plate is 5cm

2) The diameter of the plate is 20cm. (I’m sure)

I choose A, because I am not sure whether (2) is correct, sounds like also can.



6. Stickers. One book has 100 pages, one way - the first page stick blue sticker, and every six pages stick the blue stickers. The other way – first stick red sticker, then every 8pages stick red ones. Q- how many pages with out stickers?Answer choice..68, 70, 72,75….

8. A big fence, inside there is a small garden. The question is very long, but makes it simple; it means that the perimeter of the fencing of the yard is 280mm. Ask one the width of the small garden. 1) The width of the big garden is five times more than 10m the small garden. 2) The length of the fence is 59m more the small garden. 3) the width and length of the small garden.

It is very easy to calculate if understand. I do not remember the choice, but I remember I got the fence with=60, length=80, which I am sure.
