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.

Input: Consider Input: Question: Does mR spectroscopy indicate diffuse multiple sclerosis activity during remission?
Answer: The absence of early tissue atrophy and apparent axonal dysfunction (NAA loss) in these RR MS patients suggests that both are preceded by diffuse glial proliferation (astrogliosis), as well as possible inflammation, demyelination and remyelination reflected by elevated mI, Cho and Cr, even during clinical remission and despite immunomodulatory treatment.

Output: yes

Input: Consider Input: Question: Is prenatal anteroposterior pelvic diameter cutoffs for postnatal referral for isolated pyelectasis and hydronephrosis : more always better?
Answer: Using these thresholds, we could avoid a significant number of followup ultrasounds in the prenatal and postnatal periods, as well as invasive postnatal tests (ie voiding cystourethrography and mercaptoacetyltriglycine scintigraphy) without missing even a single case of obstructive nephropathy requiring surgery.

Output: no

Input: Consider Input: Question: Are ultrasound characteristics of breast fibroadenomas related to clinical and histological parameters?
Answer: Histological type, tumor size and patient age significantly influence ultrasound characteristics of breast FA. This might be helpful to consider when breast lesions are classified and decisions for biopsies are made.
Output: yes
