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.

[EX Q]: Context: The aim of this study was to elucidate the role of lysyl oxidase (LOX) and lysyl oxidase like (LOXL) 2 in pathologic wound healing after glaucoma surgery. We therefore investigated the expression of LOX and LOXL2 and evaluated the therapeutic potential of anti-LOX (GS-639556, formerly M64) and anti-LOXL2 (GS-607601, formerly AB0023) antibodies in a rabbit model of glaucoma trabeculectomy. Ocular expression of LOX and LOXL2 was investigated by immunohistologic staining at different time points after trabeculectomy. Treatment with GS-639556 or GS-607601 was initiated in rabbits immediately after trabeculectomy by giving both intracameral and subconjunctival injections. Thereafter, the antibodies were given twice a week subconjunctivally until day 30 after surgery (day of euthanization). Treatment outcome was studied by clinical investigation of the bleb and by immunohistochemical analysis of angiogenesis, inflammation, and collagen deposition. LOX and LOXL2 were both upregulated in Tenon's capsule and the conjunctiva after glaucoma surgery. Repeated administration of LOX- or LOXL2-targeting monoclonal antibodies increased bleb area and bleb survival. Analyses of immunohistologic stainings showed that both antibodies significantly decreased fibrosis, whereas the anti-LOXL2 antibody also significantly reduced blood vessel density and inflammation. Targeting LOXL2 with an inhibitory monoclonal antibody (GS-607601) reduced pathologic angiogenesis, inflammation, and fibrosis. These results suggest that LOXL2 could be an appealing target for treatment of scar formation after glaucoma surgery, and point to the potential therapeutic benefits of simtuzumab, a humanized monoclonal antibody derived from GS-607601. 
 Question: What is the drug target for Simtuzumab?
[EX A]: loxl2

[EX Q]: Context: Copper of Kargaly origin was distributed during Bronze Age over a vast territory within the steppe and forest-steppe of Eastern Europe. 
 Question: What is the product of Kargaly?
[EX A]: copper

[EX Q]: Context: In the county, the population was spread out with 23.5% under the age of 18, 7.8% from 18 to 24, 28.5% from 25 to 44, 25.9% from 45 to 64, and 14.2% who were 65 years of age or older. The median age was 40 years. For every 100 females, there were 93.8 males. For every 100 females age 18 and over, there were 90.5 males. 
 Question: Which age group is smaller: 25 to 44 or 45 to 64?
[EX A]:
45 to 64
