MEMORANDUM
To: Richard
From: Jack
Re: Alternate Freight Route
Date: January 11,10:15 a.m.
I just spoke with Allied Freight. They said that with oil over US$100 a barrel, they are imposing a 5% surcharge on all deliveries until further notice. It seems to me we have to discuss alternate freight companies. Other firms are not increasing their prices. I don’t think we have a choice for February, but we should consider which other company might offer a lower price starting in March.
I’d like to meet with you and Harold Ruskin first to go over what realistic choices we have. We can present our findings and recommendations to the Board of Directors at our next monthly meeting. Please get back to me as soon as possible. Thanks.
In the memo, the word "realistic" in paragraph 3, line 2, is closest in meaning to

A.flexible
B.practical
C.critical
D.optional
