--------------------------
Look at the subject in each sentence, please.
Are the subjects all in generic use from #1 to #4?
Does #1 mean #5 or #7?
Does #2 mean #6 or #8?
Does #3 mean #9?
Does #4 mean #10?

1 and 7 are close in meaning. 5 seems to mean that one will float, but two or more won't. It's unclear though.

2 and 8 are close. 6 seems to mean that one will float, but more than one won't.

3 and 9 are close although 3 refers to banana peels in general, and 9 seems to be referring to one in particular. **

** This relationship applies to 4 and 10, too.

Upon examining the given statements, we can deduce the following:

1. An apple floats on water.
2. A coin sinks in water.
3. Banana peels are yellow.
4. The cell phone vibrates.

Now, let's address your questions one by one:

1. Are the subjects all in generic use from #1 to #4?
No, the subjects in statements #1 to #4 are not all in generic use. Statement #3 uses a plural noun "banana peels" instead of the generic singular form "a banana peel."

2. Does #1 mean #5 or #7?
Statement #1 is a general statement about apples and water. It does not specifically refer to a single apple or any specific apples. Both #5 ("One apple floats on water") and #7 ("Any apple floats on water") could be understood as specific or general examples that illustrate the general concept mentioned in statement #1.

3. Does #2 mean #6 or #8?
Similar to statement #1, statement #2 is a general statement about coins and water. It does not specifically refer to a single coin or any specific coins. Both #6 ("One coin sinks in water") and #8 ("Any coin sinks in water") can be interpreted as specific or general examples that illustrate the general concept mentioned in statement #2.

4. Does #3 mean #9?
Yes, statement #3 ("Banana peels are yellow") and #9 ("The banana peel is yellow") convey the same information. The first statement uses the plural form, while the second statement uses the singular form.

5. Does #4 mean #10?
Yes, statement #4 ("The cell phone vibrates") and #10 ("Cell phones vibrate") convey the same message. The first statement refers to a specific cell phone, while the second statement expresses a general characteristic of cell phones.
