Given a question and a context passage, generate the answer having the word or phrase from the context passage. Here, the answer should be a shortest continous span from the passage.

Input: Consider Input: Context: We show that overexpression of Polo-like kinase 4 (Plk4) in human cells induces centrosome amplification through the simultaneous generation of multiple procentrioles adjoining each parental centriole. This provided an opportunity for dissecting centriole assembly and characterizing assembly intermediates. Critical components were identified and ordered into an assembly pathway through siRNA and localized through immunoelectron microscopy. Plk4, hSas-6, CPAP, Cep135, gamma-tubulin, and CP110 were required at different stages of procentriole formation and in association with different centriolar structures. Remarkably, hSas-6 associated only transiently with nascent procentrioles, whereas Cep135 and CPAP formed a core structure within the proximal lumen of both parental and nascent centrioles. Finally, CP110 was recruited early and then associated with the growing distal tips, indicating that centrioles elongate through insertion of alpha-/beta-tubulin underneath a CP110 cap. Collectively, these data afford a comprehensive view of the assembly pathway underlying centriole biogenesis in human cells. 
 Question: Where in the cell do we find the protein Cep135?

Output: centrosome

Input: Consider Input: Context: The Redskins primary weapon in the backfield was running back Earnest Byner, who ranked 5th in the NFL with 1,048 rushing yards, while also catching 34 passes for 308 yards and scoring 5 touchdowns. Rookie running back Ricky Ervins was also a major asset to the running attack, rushing 145 times for 680 yards for an average of 4.7 yards per carry, while also catching 16 passes for 181 yards. And when Washington was near the goal line, they usually relied on fullback Gerald Riggs, who rushed for 248 yards and scored 11 touchdowns. The Redskins offensive line, known as "The Hogs (American football)", was led by Pro Bowl tackle Jim Lachey and guard Mark Schlereth, along with four-time Pro Bowl veteran Russ Grimm. The Hogs allowed the fewest sacks in the league with just 9, 10 sacks less than the team that allowed the second-fewest. Even Washingtons special teams unit was a big threat. Running back Brian Mitchell (running back) led the NFL in punt return yards (600) and punt return touchdowns (2) with a 13.3 yards per return average, while also gaining 583 yards returning kickoffs. 
 Question: Which player had more rushing yards, Ricky Ervins or Earnest Byner?


Output: earnest byner,
