"Find the rule for constructing the row elements for each row and inser" by Vasiliy Znamenskiy
"Find the rule for constructing the row elements for each row and inser" by Vasiliy Znamenskiy: This document presents a set of sequences with missing elements, each governed by a unique underlying rule. The task involves identifying the rule that dictates the arrangement of elements within each sequence and determining the missing items indicated by question marks ("?"). The sequences vary widely in character, including numerical progressions (such as arithmetic and geometric sequences, squares, and factorials), alphabetical series, symbolic arrangements (days of the week, Greek letters, planetary symbols), and numeric sequences referencing known mathematical constructs (e.g., prime numbers, Fibonacci series, angles). Completing these sequences requires interdisciplinary analytical skills, encompassing mathematical reasoning, linguistic patterns, general knowledge of sequences in nature, and familiarity with symbolic notations from various scientific fields. This exercise aims to develop critical thinking and pattern-recognition skills across multiple domains.

What evidence suggests?
Question
A) We observe clouds of atomic hydrogen far from the galactic center orbiting the galaxy at unexpectedly high speeds, higher speeds than they would have if they felt only the gravitational attraction from objects that we can see.
What evidence suggests that the Milky Way contains dark matter?
Answer
A) We observe clouds of atomic hydrogen far from the galactic center orbiting the galaxy at unexpectedly high speeds, higher speeds than they would have if they felt only the gravitational attraction from objects that we can see.B) We see many lanes of dark material blocking out the light of stars behind them along the band of the Milky Way.
C) We see many dark voids between the stars in the halo of the Milky Way.
D) When we observe in different wavelengths, such as infrared or radio, we see objects that don't appear in visible-light observations.
E) When we look at the galactic center, we are able to observe a large black hole that is composed of dark matter.
