Can anyone help with my son's homework?

Question

This piece of homework is finding the spelling mistakes.

Some poisons that kill insects can also threten people. Often these pouders and sprays are used on corns, beans, and other plants we eat. Unless these these plants are scrubbed, we may eat a small amount of the poison.

We found out two of the misspellings ( threten -> threaten, and pouders -> powders) but the homework book said that there are 5 mistakes. I think that there is something wrong about the two "these" in the paragraph. Please help!

Answer 1

Drop the "s" in corn, as it should be singular, and use only one "these".

Answer 2

Either the book is wrong or u made a typo somewhere.

Answer 3

corns -> corn

these these -> these

Not sure about the last one...

Answer 4

threten-threaten

pouders-powders

corns-corn

thats all i can find

Answer 5

Here's what I think it should be:

     Some poisons that kill insects can also threaten people.  Often these powders and sprays are used on corns, beans, and other plants we eat.  Unless these plants are scrubbed.  We may eat a small amount of the poison.

1.  Threten - threaten

2.  Pouders - powders

3.  Indent paragraph

4.  The comma after scrubbed should be omitted.

5.  Then the 'w' should be capitalized.  

Answer 6

Well these shouldn't be in there twice. But I can't really see anything else wrong other than threaten and powders. Maybe check punctuation.  

Answer 7

power and threatends

thanks  

enjoy your sons work

Answer 8

Corns ---> Corn (already plural)

It says "these" twice in a row

"other plants we eat" ---> "other plants that we eat"

Answer 9

Some poisons that kill insects can also threten (threaten) people. Often these pouders (powders) and sprays are used on corns, beans, and other plants we eat. Unless these these (delete second "these")plants are scrubbed, we may eat a small amount of the poison.

Answer 10

threaten, powder, ....plural of corn is "corn", not corns, these these, .....

Answer 11

Unless these these plants - there should only be one "these"

corn should be singular (corn, not corns)

I don't see any others.  You may have automatically corrected something when you put it on here, though.
