Answer 1

bread mold

Answer 2

HEY

HERE IS YOUR ANSWER

1. the answer is bread mould

2.no, i dont think that he kept it in refrigerator. because he says that it is covered with whitish cotton.

3.there r so many ways through which he can know that he should not eat the sandwich.they r :-

(i) because of the presence of the sandwich.

(ii) because of the smell.

4.no, i think that the milkshake will not undergo this type of process. because it is a liquid and this type of process will only undergo in breads and in only spongy materials.

5. it would just give a slight difference in the presence and it would be smelly.
