Answer the following question given this paragraph: The valence shell is the outermost occupied shell of electrons in an atom. This shell holds the valence electrons, which are the electrons that are involved in bonding and shown in a Lewis structure. Valence-shell electron pair repulsion theory , or VSEPR theory, states that a molecule will adjust its shape so that the valence electron pairs stay as far apart from each other as possible. This makes sense, based on the fact that negatively charged electrons repel one another. We will systematically classify molecules according to the number of bonding pairs of electrons and the number of nonbonding or lone pairs around the central atom. For the purposes of the VSEPR model, a double or triple bond is no different in terms of repulsion than a single bond. We will begin by examining molecules in which the central atom does not have any lone pairs. Q: What is the outermost occupied shell of electrons in an atom. A:

OPTIONS:
- Inner Shell
- radiative shell
- modular shell
- valence shell

Answer the following question given this paragraph: Biodiversity is a measurement of the amount of variation of the species in a given area. More specifically, biodiversity can be defined as the variety of life and its processes, including the variety of living organisms, the genetic differences among them, and the communities and ecosystems in which they occur. Q: What is a measurement of the amount of variation of the species in a given area called? A:
****
A: biodiversity

Answer the following question given this paragraph: The energy effects of a wave depend on time as well as amplitude. For example, the longer deep-heat ultrasound is applied, the more energy it transfers. Waves can also be concentrated or spread out. Sunlight, for example, can be focused to burn wood. Earthquakes spread out, so they do less damage the farther they get from the source. In both cases, changing the area the waves cover has important effects. All these pertinent factors are included in the definition of intensity I as power per unit area:. Q: The energy of a wave depends on time as well as what other property of the wave? A:
OPTIONS:
- force
- power
- frequency
- amplitude
amplitude

Answer the following question given this paragraph: Q: What is the smallest unit of matter that still maintains it's properties of being an element? A:
OPTIONS:
- a cell
- an electron
- a proton
- an atom

Answer: an atom

input with options: Answer the following question given this paragraph: The first horizon is the "A" horizon. It is more commonly called the topsoil . The topsoil is usually the darkest layer of the soil. It is the layer with the most organic material. Humus forms from all the plant and animal debris that falls to or grows on the ground. The topsoil is also the region with the most biological activity. Many organisms live within this layer. Plant roots stretch down into this layer. The roots help to hold the topsoil in place. Topsoil is needed to grow most crops ( Figure below ). Q: What is the "a" horizon commonly known as? A:
OPTIONS:
- sediment
- core
- crust
- topsoil
output:
topsoil
