TASK DEFINITION: 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.
PROBLEM: 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.

SOLUTION: yes

PROBLEM: Question: Does cheating explain selective differences at high and low relatedness in a social amoeba?
Answer: These results suggest that social competition and something beyond solitary growth differences occurs during the vegetative stage when amoebae eat bacteria and divide by binary fission. The high degree of repeatability of our results indicates that these effects are strong and points to the importance of new approaches to studying interactions in D. discoideum.

SOLUTION: no

PROBLEM: Question: Is treatment of established tumor associated with ICAM-1 upregulation and reversed by CD8 depletion in a tumor necrosis factor-alpha gene transfected mouse mammary tumor?
Answer: Highly significant in vivo tumor growth inhibition and immune protection after injection with TNF-alpha-transfected tumors appears to be mediated predominantly by CD8+ T cells and ICAM-1 upregulation. These findings suggest that TNF-alpha increases recruitment and adhesion of effector T cells.

SOLUTION:
yes
