When a molten metal is mixed with another substance, there are two mechanisms that can cause an alloy to form, called atom exchange and the interstitial mechanism. The relative size of each element in the mix plays a primary role in determining which mechanism will occur. When the atoms are relatively similar in size, the atom exchange method usually happens, where some of the atoms composing the metallic crystals are substituted with atoms of the other constituent. This is called a substitutional alloy. Examples of substitutional alloys include bronze and brass, in which some of the copper atoms are substituted with either tin or zinc atoms. With the interstitial mechanism, one atom is usually much smaller than the other, so cannot successfully replace an atom in the crystals of the base metal. The smaller atoms become trapped in the spaces between the atoms in the crystal matrix, called the interstices. This is referred to as an interstitial alloy. Steel is an example of an interstitial alloy, because the very small carbon atoms fit into interstices of the iron matrix. Stainless steel is an example of a combination of interstitial and substitutional alloys, because the carbon atoms fit into the interstices, but some of the iron atoms are replaced with nickel and chromium atoms.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Tin or zinc atoms in place of copper atoms create?
Ah, so.. substitutional alloys

An example of this theory in action would be as follows: An emotion-evoking stimulus (snake) triggers a pattern of physiological response (increased heart rate, faster breathing, etc.), which is interpreted as a particular emotion (fear). This theory is supported by experiments in which by manipulating the bodily state induces a desired emotional state. Some people may believe that emotions give rise to emotion-specific actions: e.g. "I'm crying because I'm sad," or "I ran away because I was scared." The issue with the James–Lange theory is that of causation (bodily states causing emotions and being a priori), not that of the bodily influences on emotional experience (which can be argued and is still quite prevalent today in biofeedback studies and embodiment theory).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What sort of response does the stimulus cause?
Ah, so.. physiological

Various disco songs incorporated sounds produced with synthesizers and drum machines, and some compositions were entirely electronic; examples include Giorgio Moroder's late 1970s productions such as Donna Summer's hit single "I Feel Love" from 1977, Cerrone's "Supernature" (1977), Yellow Magic Orchestra's synth-disco-pop productions from Yellow Magic Orchestra (1978), Solid State Survivor (1979), and several early 1980s disco-pop productions by the Hi-NRG group Lime.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What year was solid state survivor released?
Ah, so..
1979
