Why does an e-z link card not work when it is placed in a wallet with a magnet?

the card will not be scanned as the magnet interrupts the machine that scans or it may also be becuz of the reason that the card is attracted to the magnet. anyway it is a fact to prevent keeping magnets near electronics such as mobilephones etc. so i guess that it is bcos of blocking the fieldwaves to scan the card.

Hi everyone,

Regarding all the mind-boggling questions you have asked–will only a few come out, while the rest of the questions are like those normal ones for example… those question that come out in all the exam papers from schools like Nanyang, Taonan, Nanhua, etc.

yeast is a microscopic fungus.

Robertpattinsonidle:

A green bean that can germinate when conditions are favorable is living but a cooked green bean is non-living.

DS said if this question appears in section A, his answer will be that it is a living thing.

But, if this appears in section B, he would explain the living and non-living aspects of the green bean. (e.g. seed leaves and seed coat are non-living but the plant cells residing inside the bean are living, thus the bean can grow into a plant)

P.S.
DS said that all living things can be distinguished by the following characteristics:

-Living things need air, food and water to survive
-Living things will die
-Living things can reproduce
-Living things can grow
-Living things can move about freely on their own
