input question: Extract the answer to the question from the following context. Question: What miracle does perpeual virginity imply? Context: The Perpetual Virginity of Mary asserts Mary's real and perpetual virginity even in the act of giving birth to the Son of God made Man. The term Ever-Virgin (Greek ) is applied in this case, stating that Mary remained a virgin for the remainder of her life, making Jesus her biological and only son, whose conception and birth are held to be miraculous. While the Orthodox Churches hold the position articulated in the Protoevangelium of James that Jesus' brothers and sisters are older children of Joseph the Betrothed, step-siblings from an earlier marriage that left him widowed, Roman Catholic teaching follows the Latin father Jerome in considering them Jesus' cousins.???

Problem: Given the question: Extract the answer to the question from the following context. Question: What happens to the efficiency when a fixture is shaded? Context: An important property of light fixtures is the luminous efficacy or wall-plug efficiency, meaning the amount of usable light emanating from the fixture per used energy, usually measured in lumen per watt. A fixture using replaceable light sources can also have its efficiency quoted as the percentage of light passed from the "bulb" to the surroundings. The more transparent the lighting fixture is, the higher efficacy. Shading the light will normally decrease efficacy but increase the directionality and the visual comfort probability.

The answer is:
decrease efficacy
