Context: Coming off their bye week, the Lions played a Week 5 Black and Blue Division duel at home with the Chicago Bears. In the first quarter, Detroit trailed early as Bears kicker Robbie Gould got a 37-yard field goal. In the second quarter, the Lions continued to trail as QB Kyle Orton completed a 9-yard TD pass to RB Matt Forte and a 12-yard TD pass to WR/KR Devin Hester. In the third quarter, Chicago continued its domination as Forte got a 1-yard TD run, and CB Charles Tillman returned an interception 26 yards for a touchdown. Afterwards, Detroit got its only score of the game as rookie RB Kevin Smith scored on a 12-yard TD run. In the fourth quarter, the Bears sealed the win when Gould nailed a 45-yard field goal.
Question: How was the ball received ending in the longest touchdown run?

Ex Output:
interception

Context: In cells of the immune system that are stimulated by antigen or antigen-antibody complexes, Ca(2+) entry from the extracellular medium is driven by depletion of endoplasmic reticulum Ca(2+) stores and occurs through specialized store-operated Ca(2+) channels known as Ca(2+)-release-activated Ca(2+) (CRAC) channels. The process of store-operated Ca(2+) influx is essential for short-term as well as long-term responses by immune-system cells. Short-term responses include mast cell degranulation and killing of target cells by effector cytolytic T cells, whereas long-term responses typically involve changes in gene transcription and include T and B cell proliferation and differentiation. Transcription downstream of Ca(2+) influx is in large part funneled through the transcription factor nuclear factor of activated T cells (NFAT), a heavily phosphorylated protein that is cytoplasmic in resting cells, but that enters the nucleus when dephosphorylated by the calmodulin-dependent serine/threonine phosphatase calcineurin. The importance of the Ca(2+)/calcineurin/NFAT signalling pathway for lymphocyte activation is underscored by the finding that the underlying defect in a family with a hereditary severe combined immune deficiency (SCID) syndrome is a defect in CRAC channel function, store-operated Ca(2+) entry, NFAT activation and transcription of cytokines, chemokines and many other NFAT target genes whose transcription is essential for productive immune defence. We recently used a two-pronged genetic approach to identify Orai1 as the pore subunit of the CRAC channel. On the one hand, we initiated a positional cloning approach in which we utilised genome-wide single nucleotide polymorphism (SNP) mapping to identify the genomic region linked to the mutant gene in the SCID family described above. In parallel, we used a genome-wide RNAi screen in Drosophila to identify critical regulators of NFAT nuclear translocation and store-operated Ca(2+) entry. These approaches, together with subsequent mutational and electrophysiological analyses, converged to identify human Orai1 as a pore subunit of the CRAC channel and as the gene product mutated in the SCID patients.
Question: Which calcium/calmodulin dependent protein phosphatase is involved in the activation of the family of NFAT transcription factors (Nuclear Factors of Activated T cells)?
