In sheep, this practice is used to prevent flies from laying eggs in the wool:

In range flock sheep production, white-faced breeds are usually used in the ewes because they produce good quality meat and grow rapidly.

Which country has the largest sheep population?

This breed of draft horse is the most popular in the U.S. (see below)

Currently the United States is the leader in drug-assisted therapy in the world. 

Consider the following sequence of IR code:    1. a1 = a2; 2. b1  = b2; label_0:  3. t1 = i * 4;  4. if (a1 < b1) goto label_1; 5. t2 = a1 * t1;  6. i = i + 1;  7. b2 = b1;  8. goto label_2; label_1:  9. t2 = b1 * t1;  10. i = i - 1;  11. a2 = a1;  12. if (a2 < 10) goto label_3; label_2:  13. a1 = a1 + a2;  14. b1 = b1 + b2;  15. i = i * 2;  16. goto label_0; label_3:  17. t1 = t2;  18. t2 = t2 + 2;  19. a1  = a2; 20. b1 = b2; 21. return;  Detect basic blocks and generate the control flow graph.  Write each basic block as e.g. B0 = {1, 2, 3} to show that basic block B0 contains the statements numbered 1, 2, and 3 above. Show the structure of the control flow graph as e.g. B1 = {B2, B3, B0} to show edges from B1 to B2, B1 to B3, and B1 to B0.  Perform liveness analysis on the control flow graph and show the LiveIn and LiveOut sets for each basic block.  Write the sets in the format of e.g. In[B1] = {a, b, c, ...}
