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.

Example input: Context: Architecturally, the school has a Catholic character. Atop the Main Building's gold dome is a golden statue of the Virgin Mary. Immediately in front of the Main Building and facing it, is a copper statue of Christ with arms upraised with the legend 'Venite Ad Me Omnes'. Next to the Main Building is the Basilica of the Sacred Heart. Immediately behind the basilica is the Grotto, a Marian place of prayer and reflection. It is a replica of the grotto at Lourdes, France where the Virgin Mary reputedly appeared to Saint Bernadette Soubirous in 1858. At the end of the main drive (and in a direct line that connects through 3 statues and the Gold Dome), is a simple, modern stone statue of Mary. 
 Question: To whom did the Virgin Mary allegedly appear in 1858 in Lourdes France?
Example output: Saint Bernadette Soubirous
Example explanation: This is the correct answer. Because the question is asking for the name of the person and following sentence from the passage answers it: It is a replica of the grotto at Lourdes, France where the Virgin Mary reputedly appeared to Saint Bernadette Soubirous in 1858.
Q: Context: Parkinson's disease (PD) is the second most common neurodegenerative disorder, defined by the presence of resting tremor, muscular rigidity, bradykinesia, and postural instability. PD is characterized by the progressive loss of dopaminergic neurons within the substantia nigra pars compacta of the midbrain. The neuropathological hallmark of the disease is the presence of intracytoplasmic inclusions, called Lewy bodies (LBs) and Lewy neurites (LNs), containing -synuclein, a small protein which is widely expressed in the brain. The -synuclein gene, SNCA, is located on chromosome 4q22.1; SNCA-linked PD shows an autosomal dominant inheritance pattern with a relatively early onset age, and it usually progresses rapidly. Three missense mutations, A53T, A30P, and E46K, in addition to gene multiplications of the SNCA have been described so far. Although it is clear that LBs and LNs contain mainly the -synuclein protein, the mechanism(s) which leads -synuclein to accumulate needs to be elucidated. The primary question in the molecular pathology of PD is how wild-type -synuclein aggregates in PD, and which interacting partner(s) plays role(s) in the aggregation process. It is known that dopamine synthesis is a stressfull event, and -synuclein expression somehow affects the dopamine synthesis. The aberrant interactions of -synuclein with the proteins in the dopamine synthesis pathway may cause disturbances in cellular mechanisms. The normal physiological folding state of -synuclein is also important for the understanding of pathological aggregates. Recent studies on the -synuclein protein and genome-wide association studies of the -synuclein gene show that PD has a strong genetic component, and both familial and idiopathic PD have a common denominator, -synuclein, at the molecular level. It is clear that the disease process in Parkinson's disease, as in other neurodegenerative disorders, is very complicated; there can be several different molecular pathways which are responsible for diverse and possibly also unrelated functions inside the neuron, playing roles in PD pathogenesis. 
 Question: Which is the primary protein component of Lewy bodies?
A:
αsyn
