These are antonyms!!
Resistant means that something can't affect it (the resistant object), or has a hard time affecting it. For example, water resistant shoes aren't easily affected by water; water cant pass through them as easily as non-water resistant shoes.
Yielding means that something is flexible or is influenced by another thing easily. For example, when you "yield" when driving, you are letting the other cars go before you; or, when an object "yields" to pressure, it is bending under pressure (though not quite breaking).
In summary: resistant means nothing can touch it, while yielding means that things easily affect it; thus, antonyms.
The sentence that follows the correct apostrophe rule is option C. The book's story was pretty exciting, even though its cover was not. The correct placement of the apostrophe should be on the word "book's" because it shows ownership, which means "the story of the book". The word "its" should not have an apostrophe because "it's" is the shorter term for "it is".
William Shakespeare was the son of John Shakespeare, an alderman and a successful glover (glove-maker) originally from Snitterfield, and Mary Arden, the daughter of an affluent landowning farmer. He was born in Stratford-upon-Avon, where he was baptised on 26 April 1564.
You can use the (Unique) constraint to compare one column against another column. Hope I got it right.
