Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.

Ex Input:
Question: Does a protein complex containing Inscuteable and the Galpha-binding protein Pins orient asymmetric cell divisions in Drosophila?
Answer: Pins and Inscuteable are dependent on each other for asymmetric localisation in delaminated neuroblasts. The binding of Pins to Galpha protein offers the intriguing possibility that Inscuteable and Pins might orient asymmetric cell divisions by localising or locally modulating a heterotrimeric G-protein signalling cascade at the apical cell cortex.

Ex Output:
yes


Ex Input:
Question: Does maraviroc concentrate in the cervicovaginal fluid and vaginal tissue of HIV-negative women?
Answer: Higher maraviroc exposure in the female genital tract provides a pharmacologic basis for further evaluation of chemokine receptor 5 antagonists in HIV infection prophylaxis. This is the first study to report antiretroviral VT concentrations, CVF protein binding, and CVF terminal elimination.

Ex Output:
yes


Ex Input:
Question: Is bone marrow from blotchy mice dispensable to regulate blood copper and aortic pathologies but required for inflammatory mediator production in LDLR-deficient mice during chronic angiotensin II infusion?
Answer: Overall, our study indicated that the effect of bone marrow from blotchy mice during adulthood is dispensable in the regulation of blood copper, plasma cholesterol and phospholipids levels, and aortic pathologies, but contributes to a reduction of MIP-1β, MCP-1, MCP-3, MCP-5, TIMP-1, and VEGF-A production and triglycerides concentration in plasma. Our study also hints that bone marrow transplantation cannot serve as an independent treatment option.

Ex Output:

yes
