Correct Answer: C. financial

Correct Answer: A. took up football

Explanation

The phrase started playing indicates that Osyaku began to engage in the activity of football. Let's analyze the options:

• A. took up football: The phrasal verb to take up a sport, hobby, or activity means to start doing it regularly. This perfectly matches the meaning of started playing.

• B. picked up football: To pick up a sport or skill often means to learn it, often informally or easily, or to resume something. While you might pick up the rules of a game, started playing refers to the initiation of the activity itself, for which take up is more precise.

• C. returned football: Returned means to go back to something after a period of absence. The original sentence implies a new beginning, not a resumption.

• D. took up with football: To take up with usually means to begin to associate with someone or something, often in a close or intimate way, or sometimes in a problematic way. It doesn't mean to start playing a sport.

Based on the definitions, took up football is the closest in meaning to started playing football.

Correct Answer: C. the function of a multicellular organism is the sum total of the functions of its constituent cells

Explanation

The correct answer is C. Here's why:

• A. multicellular organisms are made up of cells: This statement is true and explains why the cell is the *structural* unit, but not fully why it's the *functional* unit.

• B. all cells in a multicellular organism function as a single cell: This is incorrect. Cells in a multicellular organism are specialized and perform diverse functions. They work together but do not act as one undifferentiated cell.

• C. the function of a multicellular organism is the sum total of the functions of its constituent cells: This is the most accurate explanation. All life processes, from metabolism and reproduction to response to stimuli and growth, ultimately occur at the cellular level. Whether it's a muscle contracting, a neuron transmitting a signal, or a gland secreting hormones, these are all functions performed by individual cells or groups of cells working in concert. The overall functioning of the organism is the emergent property of the collective and coordinated functions of its cells.

• D. the function of a single cell is superior to that of the multicellular organism: This is incorrect. A multicellular organism, through cell specialization and cooperation, can perform far more complex and advanced functions than any single cell alone.
