### Instruction:

Extract the cause and effect entities from the following sentence:
Requirement: the spectral range shall be 1.0-2.0 micron (required, <1.0 to >2.0 micron goal) to ensure the detection of spectral features expected for the redshift distributions of the galaxy samples

CONDITION: to ensure
CAUSE_1: the spectral range shall be 1.0-2.0 micron
EFFECT_1: to ensure the detection of spectral features expected for the redshift distributions of the galaxy samples
NOT_RELEVANT: (required, <1.0 to >2.0 micron goal)
