Pain in the English

Working from a textbook, one exercise requires students to find the error in different sentences. Can anybody find the error in the following sentence?

*The painting of the Buddha, that has nine figures, made the religion more concrete to believers in 13th-century Tibet.*

The sentence refers to a picture in the book of a painting of a Buddha with several other figures (bodhisattvas) around it.

Sections of the sentence is underlined. I will use square-brackets to indicate the underlined sections. The error should be with one of these underlined sections. Here is the sentence again:

The painting of the Buddha[, that has]{A} nine [figures,]{B} made the religion more [concrete]{C} to believers in [13th-century Tibet.]{D}

The Teacher's Edition of the textbook says that the error is with {A}. If this is correct, what is wrong with it?

Thanks!

I need to list the people in a photo, below the photo. The picture will be framed, not in a magazine, etc. What is the proper punctuation? The way I originally typed the names follows but I am ready to finalize the layout and want to know the proper format. The way I have it now:

1. Catherine, March 11, 1874; 2. Alice Bell, July 8, 1875; 3. Birdie Alberdine, February 14, 1877; 4. Mary Adella, November 15, 1879… and so on for eight people.

If I number each person, is additional punctuation required between the names as I have typed it or do the numbers stand alone? Should the individual names even be numbered? I am really not certain what the proper format is.

I am on a deadline to complete this restored photo and layout for a client so a prompt reply would be greatly appreciated.

So, for a last name like “Stachewicz”…would it be The Stachewiczs or the The Stachewiczes?

Is it appropriate to use a bulleted list in a question? Example:

Which type of flour would you use for the following items:
– bread
– cake
– cookies

Would you put a question mark at the end of each bullet? Would you only use a question mark at the end of the last bullet? Does the sentence need to be re-worded?

If our organization is called Help for Kids and we want to use the abbreviation HFK . . . is this correct usage in this sentence:
HFK' activities will start in the summer. With the K standing for Kids and Kids being plural, would this be correct use of the apostrophe at the end of HFK'?

I have a sentence with which I am struggling because I am not sure if I can use both a colon and semi-colon in it. However, I want everything in one sentence and cannot figure out what other punctuation I should use. Here's the sentence with names and details altered for anonymity.

“I am indebted to my family, especially my cousins: Jane Smith, my first teacher, without whom I would not be where I am today; and John Smith, my second teacher, who taught me more than he could have possibly imagined.”

The colon is setting up a list and the semi-colon is separating items in the list that contain commas. Thoughts? Thanks in advance.

I recently gave a class of six year olds a spelling test and saw that many of the children were spelling words with the correct letters but had used capital letters at the beginning, middle or end of a word. Is a word that has the correct letters but some of them are in capitals still considered to be correctly spelled?

“Do's and Don't's” is a popular phrase, but the punctuation of it seem to vary for “don't's”. What should it be?

Dont's

or

Don't's

While waiting for the subway to arrive, I noticed this mysterious symbol between “PRINCE” and “ST.” This is not a mistake of any kind. All of the signs at the station had this little triangle, and whoever created these signs put a significant amount of effort in inserting it. (Just look at how it is tiled.) Obviously this was something important for the artist who created this mosaic sign. What could it mean? It could not be a dash. Firstly, a dash would be inappropriate for this context. Secondly, if it were meant as a dash, it would have been much easier to draw a straight line out of these square tiles (instead of a triangle).

(FYI: This is New York City.)

I constantly see apostrophes used in ways I believe are incorrect. I am wondering anyone can confirm for me, though.
For example, I often see “Temperatures will reach the high 90's today…”

Aren't apostrophes only used to show possession or in contractions? For example, “This sweet ride isn't (cont.) mine; it's (cont) Jessica's (poss).”

Also, how would I word something to the effect that everyone is coming to the house that my husband, Mike, and I own?

“Everyone is coming to Mike's and my house.”?
