Answer: A.  Special event
Explanation:
Special events are occasions where the customers and the company get to meet face to face and talk about products and services on offer. Special events are very ideal for product launches, or trade shows where the company aims to sell more of what it has. 
Isaac Mizrahi most probably just launched the new book and so this special event is a way of marketing it to the public through face-to-face contact.
 
        
             
        
        
        
Answer:
This implies that bus is an inferior good and car is a normal good. 
Explanation:
Initially, Jim's income was $5000 a year.
As his income increases to $60,000 a year, he decides to buy a car instead of using the bus.  
In other words, with the increase in income, the demand for traveling by bus is declining.  
This implies that it is an inferior good.  
The demand for the car is increasing with an increase in income.  
So, the car is a normal good.  
An inferior good can be defined as a product that shows negative elasticity. This means with an increase in income its demand declines an vice versa. 
A normal good can be defined as a product that shows positive income elasticity. That is, its demand increases with rise in income and vice versa.
