Answer:
Here is a structured pseudocode that describes how to buy a new shirt, including at least two decisions and two loops:
```
procedure buy_shirt()
declare
desired_color: string
desired_pattern: string
desired_size: string
desired_price: integer
found_shirt: boolean
begin
print "What color shirt do you want?"
read desired_color
print "What pattern do you want?"
read desired_pattern
print "What size do you want?"
read desired_size
print "What price are you willing to pay?"
read desired_price
found_shirt := false
while not found_shirt do
print "Searching for a shirt..."
for each shirt in store do
if shirt.color = desired_color and shirt.pattern = desired_pattern and shirt.size = desired_size and shirt.price <= desired_price then
found_shirt := true
break
end if
end for
end while
if found_shirt then
print "Found shirt!"
print shirt.color, " ", shirt.pattern, " ", shirt.size, " ", shirt.price
print "Do you want to buy it?"
read answer
if answer = "yes" then
buy shirt
end if
else
print "No shirt found."
end if
end procedure
```
This pseudocode includes two decisions: one to determine whether the desired shirt has been found, and another to determine whether the user wants to buy the shirt. It also includes two loops: one to search the store for the desired shirt, and another to allow the user to enter their answer.
